    Abstract—Computational Fluid Dynamics is a popular modeling approach which utilizes numerical methods and computer simulations to solve and analyze problems that involve transport phenomena in fluid flows. CFD-based models demonstrate high versatility and capability of dealing with a wide range of engineering problems. 1.1.What is a User-Defined Function? A user-defined function, or UDF, is a C function that can be dynamically loaded with the ANSYS Fluent solver to enhance its standard features. For example, you can use a UDF to: • Customize boundary conditions, material property definitions, surface and volume reaction rates, source
