What is the Radial Basis Function (RBF) Morph / Mesh Morphing?
Mesh morphing involves adapting a computational grid for computeraided engineering (CAE). For instance, the solid or shell mesh of a structural part ready to be processed by an FEA solver, or the volume mesh complete with boundary conditions for a CFD solver, can take a new shape by just updating nodal positions. This means that the mesh’s topology (node count, cell count, connectivity) stays the same. Only the nodes’ x,y, and z coordinates in the part of the model undergoing a shape modification are updated. Mesh morphing can be used for different purposes: create shape parameters (i.e., change a length, an angle, a thickness), move onto a new known shape (i.e., as manufactured, as designed by CAD), move onto a body predicted by the CAE solution (automatic shape optimization with adjoint or BGM), and support multiphysics (move CFD mesh according to the evolution of the FEMconnected one, enable erosion/deposition).
Usually, mesh morphing is faster than remeshing for many reasons: it avoids “meshing noise” (having the same mesh adapted means the effect of a parameter is not confused with the impact of a new mesh structure), so variation effects can be assessed even with a coarser mesh. The CAE model can be updated in the background, keeping all the original settings (boundary conditions). The update of nodal positions usually requires less computational effort vs. a complete mesh regeneration. Creating shape parameters with mesh morphing is faster than creating a parametric CAD model.
RBFs are a mathematical tool capable of interpolating available fields on a cloud of points. Mesh morphing defines a displacement field on a cloud of source points (usually some of the surfaces/curves of the CAE mesh). It then propagates it on a cloud of target points (usually the nodes of the volume/surface mesh of the CAE model undergoing adaption). The method fits very well with mesh morphing needs: its meshless nature allows you to easily manage partitioned meshes used for highperformance parallel computation (HPC); its nodewise nature will enable you to have complete control of specific areas. The computational cost of RBF can be very high, so specific algorithms (Fast Radial Basis Functions) are required to enjoy such benefits for industrial applications.
Reducedorder models (ROM), as suggested by their name, are numerical models of a system (fluid, structure, or other physics) capable of working very fast (typically in realtime). ROM is defined by adopting datacompression algorithms and applying them to many different instances (also known as snapshots) of the original model to be reduced.
RBF and ROM are not intended to improve meshing but rather allow for a link between CAE/meshing and the implementation of realtime Digital Twins. RBF is, in fact, a method of mesh morphing that supports the automatic generation of shape variations of the original mesh. Some distortion of the cells undergoing the deformation (stretching/compression) usually occurs, and a suitable mesh morphing method must preserve the quality of the morphed mesh. RBF is proven to be one of the best solutions nowadays available to implement highquality mesh morphing: the core of the mesh is adapted with minimum distortion, and the distribution of mesh size close to the surfaces (boundary layers to capture the flow, refinement layers to capture stress raisers) is very well preserved.
Radial Basis Function (RBF) Morphing is a technique that is utilized in computational mechanics, computer graphics, and, most specifically, finite element simulations. It is also known as Mesh Morphing. The deformation of a mesh can be controlled by the application of this mathematical technique by making use of radial basis functions.
The following is an abbreviated explanation of the idea:
The creation of a new mesh from an existing one requires some initial mesh distortion in order to do RBF morphing. A group of control points are responsible for directing the deformation. A realvalued function whose value is determined only by the distance from the origin, a radial basis function is associated with each control point in the network. This function’s value is known as the radial basis value.
Moving the control points produces the new mesh by altering the shape of the related radial basis functions, which in turn alters the shape of the mesh itself. In computer graphics, the RBF morphing approach is used frequently for tasks such as facial animation. In engineering, the technique is utilized for parametric studies in situations in which the shape of a model needs to be updated systematically.
In markdown format, the following is a straightforward representation of the concept:
 Original Mesh
The process of morphing begins with the original mesh, which serves as the basis for the new mesh.
 Control spots
These are certain spots picked on the mesh that will guide the deformation. Control points are also known as control nodes.
 Radial Basis Functions
Each of the control points has a radial basis function that is connected with it.
 Deformed Mesh
When you move the control points, the shape of the radial basis functions shifts, which in turn causes the mesh to take on a new form.
How can RBF Morph CFD simulation be applied in Engineering?
RBF Morph is a tool that extends the capabilities of morphing that are available in ANSYS’s CFD (Computational Fluid Dynamics) simulation software. It is an addon for ANSYS. It is very helpful in the subject of engineering for a number of reasons, including the following:

Mesh Morphing MR CFD Projects
The following is a list of possible subject areas for a Mesh Morphing MR CFD Project.
– Morphing of the RBF Mesh Used in Aerodynamics
Research should be done on how RBF mesh morphing can be applied in the field of aerodynamics. For this purpose, RBF mesh morphing might be used to model the aerodynamics of a variety of various shapes and structures.
NACA0012 Airfoil Optimization With RBF Morph, CFD Simulation Ansys Fluent Training
The Ansys Fluent program was used to do the initial simulation in this research, which modeled the flow that occurs within a NACA0012 airfoil. The angle of attack is 1.53 degrees, and the simulation was carried out via a densitybased solver because the compressibility required it. The simulation was run at a Mach number of 0.7. After that, the geometry is worked on to improve the lifttodrag ratio (also known as L/D), which is a measure of aerodynamic efficiency. The Ansys Fluent program operating within the Ansys Workbench environment was responsible for performing all of the optimizations. The step of optimization consists of three distinct stages of execution. Only the movement of points in the vertical direction was taken into account in the first step, and the best answers were found for the maximum lifttodrag ratio and the maximum lift coefficient. The lifttodrag ratio was calculated for two new modes after each of these two ideal solutions was considered for horizontal displacement in the subsequent phase. Following optimization, we were successful in locating the spots that provided the greatest possible lifttodrag ratio.
Maximizing Lift to Drag Ratio by Adjoint Solver (RBF), ANSYS Fluent CFD Simulation Tutorial
This research is concerned with the application of the Ansys Fluent software to a numerical simulation of the Lift to Drag Ratio on an Airfoil. We plan to use an adjoint solver and a gradientbased optimizer in order to make this model’s design as efficient as possible.
When it comes to aerodynamics, one of the most frequent topics of discussion for engineers and designers is the investigation of the performance of airfoils. When it comes to aerodynamic performance, having an optimal design is of the utmost importance. Both lift and drag are essential forces that contribute to aerodynamics. The force of drag is exerted in the same direction as the flow, while the force of lift acts in the opposite direction of the flow.
Because the drag force acts in the opposite direction of the movement of the airfoil, it slows down the movement of the airfoil. Because the lift force acts in an upward direction, it is a contributing factor that helps in the process of overcoming the weight force. Therefore, to increase the performance of the airfoil, it is necessary to decrease the amount of drag while simultaneously increasing the force of lift. As a consequence of this, our objective in this challenge is to maximize the lifttodrag ratio.
The simulation is carried out in three distinct steps. To begin, we will run the simulation using the normal flow. In the second phase, we make use of the adjoint solver to perform an analysis of the Sensitivity. In the final step, we alter the design of the model in order to attain optimal performance using the gradientbased optimizer.
A sequence of data that is expressed in the form of sensitivity analysis is provided by the adjoint solver. Our primary concern is shape sensitivity. This tool determines which aspects of the geometry have the most significant impact on the overall performance of the system.
Therefore, we must establish a target parameter. Observable is the name given to this output parameter. We are required to make use of something called an Operation in order to define a combination of observables. In the work that we have done so far, the lifttodrag ratio has been operationally established.
The lifttodrag ratio that is applied to the airfoil is the foundation for the adjoint solver. It has a bigger impact on the lifttodrag ratio anywhere there is a greater display of Sensitivity, such as when there is displacement of the border or deformation of the shape of the design.
In the gradientbased optimizer, we make use of the results from the sensitivity analysis. Using this tool, we may specify the changes that should be made to the operation. For instance, one of the things that we are looking into for this project is increasing the lifttodrag ratio. Changing the geometry of the airfoil in order to maximize the ratio is necessary. The result of these modifications should be an improved design.
As was said earlier, the current simulation is carried out in a series of three successive steps. As a result, we proceeded to evaluate the results in three stages. We were able to get velocity and pressure contours by the use of standard flow modeling. These contours illustrated the various distributions of velocity and pressure that existed throughout the domain. In the adjoint solution, we analyzed the Sensitivity. We were able to determine the contour of the form sensitivity around the airfoil.
The leading edge of the airfoil has the least Sensitivity, while the trailing edge has the most. This indicates that the amount of lift to drag ratio is most sensitive to changes in boundary displacement and shape deformation in these particular regions of the aircraft. Therefore, if we want to enhance the ratio, we need to concentrate on the trailing edge of the airfoil. The gradientbased optimizer’s ultimate solution involves the geometry going through some deformation.
Minimizing Drag Force by Adjoint Solver (RBF), ANSYS Fluent CFD Simulation Training
This project is about utilizing the program Ansys Fluent to perform a numerical simulation of the drag force that is exerted on a straightforward cylindrical obstruction. We plan to use an adjoint solver and a gradientbased optimizer in order to make this model’s design as efficient as possible.
These kinds of models are constructed in three steps. To begin, we will run the simulation using the normal flow. In the second phase, we make use of the adjoint solver to perform an analysis of the Sensitivity. In the final step, we alter the design of the model in order to attain optimal performance using the gradientbased optimizer.
A sequence of data that is expressed in the form of sensitivity analysis is provided by the adjoint solver. Our primary concern is shape sensitivity. This tool determines which aspects of the geometry have the most significant impact on the overall performance of the system. Therefore, we must establish a target parameter. Observable is the name given to this output parameter. We have characterized the drag force as observed in the study that we are presenting here.
As a result, the adjoint solver is formulated on the basis of the drag force that is exerted on the cylinder. It has a bigger impact on the drag force wherever there is a greater display of Sensitivity, which can be interpreted as a displacement of the border or a deformation of the shape of the design.
In the gradientbased optimizer, we make use of the results from the sensitivity analysis. With the help of this tool, we may specify the manner in which the observable should be altered. For instance, one of the goals that we have for this project is to reduce the amount of drag force. This necessitates a modification to the design of the cylinder in order to reduce the amount of drag. The result of these modifications should be an improved design.
As was said earlier, the current simulation is carried out in a series of three successive steps. As a result, we proceeded to evaluate the results in three stages. We were able to get velocity and pressure contours by the use of standard flow modeling. These contours illustrated the various distributions of velocity and pressure that existed throughout the domain.
The pressure contour reveals that the area in front of the cylinder, which is situated so that it is immediately in the route that the water takes, has the maximum pressure. The velocity contour also reveals a wake that is produced by fluid separation and is located behind the cylinder. In the adjoint solution, we analyzed the Sensitivity. We were able to determine the contour of the shape sensitivity around the cylinder.
The cylinder’s upper and lower halves, specifically, display the greatest levels of Sensitivity. This indicates that the quantity of drag force is most sensitive to changes in shape and boundary displacement in these regions of the body. Therefore, in order to lessen the amount of force exerted by the drag, we need to concentrate on the upper and lower regions of the geometry. The gradientbased optimizer’s ultimate solution involves the geometry going through some deformation.

Submarine Design Optimization using RBF Method CFD Simulation, ANSYS Fluent Tutorial
Through the use of the adjoint solver provided by the ANSYS Fluent software, the purpose of this simulation is to optimize the design of a submarine. The body of a structure is subject to forces from the fluid whenever the structure is moving at a particular speed inside a fluid that is continuous. For instance, the body of a submarine will experience forces exerted by the surrounding water as the submarine moves through the sea. The drag force is one of the important forces that has been explored.
This force is given to the body of the submarine in a direction that is horizontally opposed to the direction in which the submarine is moving. Therefore, the movement of the submarine is met with resistance as a result of this force. As a result, research into the drag force exerted by the submarine was included in this study. When designing and building submarines, one of the most important considerations to make is how to minimize the drag force. It is dependent on the geometric structure and dimensions of the submarine body as to whether or not the drag force is decreased or increased.
During the optimization phase, a CFD analysis of the drag force that is applied to the submarine is carried out in order to produce an adequate geometry. There are numerous different approaches to improving the body’s design through optimization. In order to do geometric optimization, the ANSYS Fluent program makes use of an adjoint solver tool. By carrying out a solution procedure, this tool is able to bring about modifications in the dimensions of the geometry that is being targeted. These alterations will continue until a geometry with the desired properties is achieved.
In order to lessen the effect of the drag force, this simulation makes use of an optimization procedure that is based on an adjoint solver. The adjoint solver tool is used to do the optimization process, which is done in three parts. To begin, the simulation was run in standard mode within the Ansys Fluent software using a fundamental geometry for a submarine as the starting point.
In this mode, the calculation of the drag force takes place. The adjoint solution is employed in the second stage, which involves identifying a target parameter, which in this case is the drag force. Using the adjoint solution, one may determine which regions of the undersea geometry are most sensitive to the total amount of drag force.
It is now possible, as a result of this work, to determine which geometrical modifications in which regions of the geometry contribute to geometrical optimization. In the third stage, the process of optimization has been completed based on a set percentage, with the goal of lowering the objective parameter (drag force).
The investigation into the drag force was carried out once the simulation had been completed. During the preliminary stages of the modeling process, the drag force was estimated to be 11.485855 N. The adjoint solver was utilized to execute an optimization operation, and the final result was that the drag force was equal to 6.4377518 N. This results in a 44% decrease in the amount of force exerted by the drag. Therefore, it is safe to say that the model’s optimization was carried out appropriately.
The modification of the model’s geometry allowed for the achievement of this decrease in the amount of drag force. As a consequence of this, adjustments were made to the model’s dimensions. Checking the range of modifications both before and after optimization has been done with the use of the program called isoclip.
Both the crosssection and the sidesection dimensions have been looked into for their dimensional shifts. The dimensions of the crosssection have been altered to now read 0.4386431*0.453043, down from the previous value of 0.5066175*0.5063399. The dimensions of the side section are now 4.09195906 and 0.5952543, down from their previous value of 4.353052 and 0.6.
Because the drag force is proportional to the crosssectional area, decreasing the crosssectional area results in a reduction in the amount of force exerted by the drag. The findings of this simulation provide further evidence that this problem exists. In addition, the total pressure and frictional forces that contribute to the drag are added together to arrive at the total drag force.
The divergence in water pressure that exists between the two sides of the submarine is what causes the phenomenon known as pressure drag. Therefore, the pressure difference will be reduced in proportion to the submarine’s decreased crosssectional area. The surface of the submarine’s sides also affects the amount of frictional drag. Therefore, the drag force will be reduced the more the side surface of the submarine is submerged.
Minimizing Pressure Drop by Adjoint Solver (RBF), ANSYS Fluent CFD Simulation Training
This project involves the use of the program Ansys Fluent to perform a numerical simulation of the pressure drop that occurs in a tube that has a Ushaped bend in it. We plan to use an adjoint solver and a gradientbased optimizer in order to make this model’s design as efficient as possible.
These kinds of models are constructed in three steps. To begin, we will run the simulation using the normal flow. In the second phase, we make use of the adjoint solver to perform an analysis of the Sensitivity. In the final step, we alter the design of the model in order to attain optimal performance using the gradientbased optimizer.
A sequence of data that is expressed in the form of sensitivity analysis is provided by the adjoint solver. Our primary concern is shape sensitivity. This tool determines which aspects of the geometry have the most significant impact on the overall performance of the system. Therefore, we must establish a target parameter. Observable is the name given to this output parameter. In the work that we are presenting here, the pressure drop has been defined as observable.
Therefore, the pressure drop in the tube serves as the foundation for the adjoint solution. It has a bigger impact on the pressure drop wherever there is a greater display of Sensitivity, whether that be a displacement of the border or a deformation of the shape of the design.
In the gradientbased optimizer, we make use of the results from the sensitivity analysis. With the help of this tool, we may specify the manner in which the observable should be altered. For instance, one of the goals that we have for this project is to reduce the pressure drop. This entails making adjustments to the pipe shape in order to reduce the pressure drop. The result of these modifications should be an improved design.
As was said earlier, the current simulation is carried out in a series of three successive steps. As a result, we proceeded to evaluate the results in three stages. We were able to get velocity and pressure contours by the use of standard flow modeling. These contours illustrated the various distributions of velocity and pressure that existed throughout the domain.
The pressure contour demonstrates that there is a decrease in pressure experienced by the fluid flow after it has traveled through the pipe bend. In the adjoint solution, we analyzed the Sensitivity. Inside the tube, we were able to determine the form sensitivity contour.
The area close to the pipe bend demonstrates the greatest level of Sensitivity. This indicates that the value of pressure drop is more sensitive to changes in boundary displacement and shape deformation in these regions of the system. Therefore, in order to lessen the pressure loss, we need to concentrate on the geometry of the bend. The gradientbased optimizer’s ultimate solution involves the geometry going through some deformation.
Elbow Optimization with RBF Morph, CFD Simulation Ansys Fluent Training
The approaches of geometry optimization have seen a significant amount of development in recent years, which has led to improved performance in mechanical devices. Mesh morphing, often known as RBF, is one of these approaches. In the process of mesh morphing, the surface of the lattice can be reshaped while the topology remains unchanged. This technique first establishes a displacement field on a cluster of origin points, and then it propagates that field onto a cluster of destination points.
The Ansys Fluent software is used initially in this project to perform a simulation of the flow that occurs within an elbow. Following that, the geometry is adjusted utilizing the morphing mesh optimization approach in order to achieve fewer pressure drops.
When there is a difference in the pressure at two different sites in the fluid carrier network, a pressure drop will result. Pressure drop or pressure loss will take place whenever a liquid substance enters one end of a piping system and exits the other. This happens when the liquid material travels from one end of the system to the other. The pressure drop that occurs across a segment of pipe, a valve, or an elbow is magnified when the flow velocity is high, and the viscosity of the fluid is high. When the velocity is low, the pressure drop will be little or nonexistent.
In this simulation, the pressure contour demonstrates that as the elbow bend is made longer, the regions on the geometry’s periphery see a greater increase in pressure. Additionally, as a consequence of the effect of this elongation, the interior regions of the curve are subject to a greater amount of pressure. On the other hand, it appears from the velocity contour that the velocity in the bending zones has, on the whole, slowed down. As a result, one may conclude that the pressure drop has been reduced as a direct result of improving the geometry, which was made abundantly evident by the value of the optimization diagram.
