Description

User-Defined Function (UDF) CFD Simulation Training Course, ANSYS Fluent

This course, User-Defined Function (UDF) CFD Simulation, is designed to provide an in-depth understanding of User-Defined Functions (UDFs) in the context of ANSYS Fluent, a Computational Fluid Dynamics (CFD) software. UDFs let you modify and improve ANSYS Fluent’s default functionality by including your procedures. They offer a means of altering the behavior of the Fluent solver at many levels, such as source terms, boundary conditions, and material attributes.

Training Course Syllabus

Our “User-Defined Function (UDF) Training Course” offers a comprehensive syllabus that includes an introduction and nine unique UDF macro products. The course  provide a deep understanding of each macro, its application, and how to implement it in your Fluent simulations effectively.

Chapter1:User-Defined Function (UDF) Concepts

This chapter will give a general introduction to User-Defined Function (UDF) and an overview of its capabilities. This section contains the following subsection:

  • USer-Defined Function (UDF) in ANSYS Fluent software
  • UDF running methods (Compiling and Interpreting)
  • Mesh Terminology (Mesh Component, Structure Data, Threads, Pinters, …)
  • Model-Specific Macros category
  • General Purpose Macros category
  • Multiphase Macros category
  • Discrete Phase Model (DPM) Macros category
  • Dynamic Mesh Macros category
  • Additional Macros category

Chapter2: DPM-Drag Macro, UDF, Drag between Particles and Fluid 

In this chapter we simulated a simple chamber that is a place for spraying discrete particles, using User-Defined Function (UDF) and DPM-Drag-Macro to write UDF programming. we define a relation to define the drag force between discrete particles and continuous fluid.

Chapter3: Mass Transfer Macro, UDF, Evaporation and Condensation Rate

this chapter uses mass_transfer Macro to write UDF programming considering a chamber inside which several rows of tubes are placed. Water vapor enters from the chamber’s top and exits from the bottom. Liquid water also passes through the internal tubes of the chamber. to model the phenomenon of evaporation and condensation a Mass Transfer between liquid water and water vapor is needed.

Chapter4: DeltaT Macro, UDF, Time Step Control

In this chapter, DeltaT Macro is used to write UDF programming for a simple tank where the water flow enters the tank from the inlet opening on the top of the tank. The purpose of this problem is to fill the tank over time.

Chapter5: Source Macro, UDF, Momentum Source Term

We used Source Macro to write UDF programming in order to simulate a simple channel in which water flows and a porous medium is in the middle of this channel. Since the direction of the fluid flow is along the z-axis, we define the source term for the momentum-z equation using a User-Defined Function (UDF).

Chapter6: CG-Motion Macro, UDF, Reciprocating Motion

In this chapter, we want an object to move within a domain using the Dynamic Mesh model. So, we define a User-Defined Function (UDF) to apply a translational movement to the object. for this purpose we need to use the CG-Motion Macro (DEFINE_CG_MOTION macro) for this UDF.

Chapter7: Init Macro, UDF, Initial Temperature

This chapter considers a simple double-pipe heat exchanger and uses Init Macro to write UDF programming to simulate heat transfer which leads to heating the outer tube and cooling the inner tube.

Chapter8: Prandtl-K Macro, UDF, Prandtl number

In this chapter, we used Prandtl_K Macro to write UDF programming for a simple channel with a turbulent fluid flow inside. To simulate the flow with a standard k-epsilon  model we have to define the Prandtl number for each of the equations of this turbulence model.

Chapter9: Profile Macro, UDF, Pressure Profile

This chapter considers a sample part of a simple urban area including some volumes as apartments and assuming the space between two rows of apartments as a street and traffic area. We define a relation according to which the pressure varies with height, so we use Profile Macro to write UDF programming.

Chapter10: Property Macro, UDF, Viscosity Relation

Using Property Macro to write UDF programming for a simple pipe with water fluid flowing inside is in this chapter. The water flow enters the pipe at a low speed and is affected by the thermal boundary condition of the pipe wall. The Viscosity varies with temperature so we use a function describing the viscosity regarding temperature.

    Kolby Kunde DDS –

    I really appreciated the wide range of macros covered in this UDF Training Course. It provided a thorough understanding of how to tailor Fluent to my specific simulation needs. Could you please illustrate with an example how using UDFs greatly enhanced a particular CFD project compared to using Fluent’s in-built functions alone?

    • Avatar Of Mr Cfd Support

      MR CFD Support –

      Thanks for the kind words. UDFs can expand the capabilities of ANSYS Fluent by giving you the flexibility to define custom functions specific to your project. For instance, in a project concerning optimal airfoil design, a UDF was used to continuously adjust the angle of attack based on the real-time flow characteristics. This allowed for a more dynamic simulation and provided insights that wouldn’t be possible with Fluent’s standard functions. The UDF enabled a precision control to simulate the airfoil performance at various angles, leading to an optimized design that performed significantly better than what was initially estimated using the default settings. This illustration shows how UDFs can be crucial for getting accurate, project-specific results that exceed Fluent’s basic functionality.

    Burdette Gibson –

    This UDF CFD Simulation course sounds very comprehensive! I’m particularly interested in the Init Macro chapter. Could you tell me more about how this macro is used in the double-pipe heat exchanger simulation?

    • Avatar Of Mr Cfd Support

      MR CFD Support –

      The Init Macro is used to specify initial conditions for your simulation. In the double-pipe heat exchanger simulation, the Init Macro would be used to set the initial temperature distribution within the computational domain. So, at the start of the simulation, the outer tube will be set to a certain temperature to simulate heating, while the inner tube is set to a different temperature to represent cooling. This provides a starting point for the simulation to proceed with heat transfer analysis.

    The course seems comprehensive. Could you provide an example of how a UDF has been practically implemented in a CFD simulation within your course material?

      In the training course, specific examples include the use of a drag-related UDF when simulating interactions between fluid flow and particles in a spray chamber, and applying source term UDFs to model the momentum variation in the presence of a porous medium. Each practical implementation is thoroughly explained with step-by-step instructions to enable learners to apply UDFs in their own simulations effectively.
