Dynamic Mesh

Mr-CFD offers a complete range of CFD analysis, consulting services and training in Dynamic mesh projects

Dynamic mesh

In Most CFD project, we design geometry, create a static mesh for this geometry and simulate this in by fix mesh. But sometimes we want to move some boundary or we have deforming shape during times. We must use dynamic mesh method. For example in mots aerodynamic problem we use fix mesh for our simulation but you can imagine there are two airplanes that are getting closer and you want to know effect of fluid flow behavior around airplanes and determine interaction between them during the time. So the relative position them are changing during time and should be modeled using dynamic mesh method. By using this method, mesh size and shape will be changed. If we use re-meshing or layering method, number of element also will be changed. Dynamic mesh method is entirely different from moving and sliding mesh also moving reference frame. In moving mesh whole zone rotate or translate in some direction but in dynamic mesh method boundary start to translate or transform. We can apply a predefined velocity by UDF or profile for boundaries or velocity of an object can be predicted based on fluid flow and gravity force balance. If we want to know the velocity of object based on this balance we should use SIX DOF dynamic mesh method.

Mesh quality during change should be conserved.ANSYS fluent has three different methods for changing mesh, smoothing, re-meshing, and layering.

We are highly experienced in using dynamic mesh in various CFD project and in the following, you can see a summary of our project related to using this module:

• Six DOF dynamic mesh for modeling variation of location and angle of ship and boat in wavy sea situation
• Simulation of the tidal turbine using six DOF dynamic mesh method (calculating rotation speed)
• Releasing of food box form airplane using six DOF dynamic method
• Simulation of globe valve movement during the time
• Train movement in the tunnel by variable velocity function in a urban tunnel
• Simulation of flap movement of an airplane wing
• Falling boxes into the water tank
• Modeling the underwater vehicle in Submerged and non-submerged situation
• Solid fuel combustion and modeling solid height level during burning fuel
• Fluid solid interaction of blood flow and vessel
• FSI simulation blood flow pumping ina human heart
• Fluid solid interaction of airflow around building and finding final deflection and fluctuation (two way and one way FSI)
• Two and four-stroke internal combustion engine engine
