Solver Setup using Ansys Fluent — Lesson 3

Great care needs to be taken during simulation setup in order to obtain an accurate simulation. The solver setup includes steps such as setting up the numerical methods, solution controls, simulation run parameters and more. In this lesson, we will be discussing how to set up and configure a CFD simulation for aerodynamic analysis of an FSAE car using Ansys Fluent. Here, we will understand in detail how to define the boundary conditions for airflow moving over an FSAE car at 35 mph. Also, we will learn how to define MRF zones for wheel rims to model the flow at wheel rims accurately. Additionally, we will learn about the robust GEKO (Generalized k-omega) model to solve the complex flow field around an FSAE car. Finally, we will learn how to monitor the convergence of the solution using residuals and report definitions.

Bonus Material – Extracting Coordinates of Points and Axis

While setting up a solver and post-processing results of the simulation, there are instances in which we need to specify coordinates of various locations. Generally, these coordinates are identified at the CAD level itself. In this bonus video, we will learn how to extract the coordinates of points and wheel rotational axis using Ansys Discovery.
