Hey, so I checked the setup, and there are some things that need to be fixed. In general, I suggest you re-create the setup from this tutorial: Aerodynamic Flow Behavior Around a Vehicle Tutorial | SimScale , that uses the Standard mesher. These recommendations can help you with convergence, which doesn’t look good at the moment.
Some things I noticed in your project:
- There are two faces that were assigned as Pressure Outlet, even though they are part of the car’s body(no-slip walls):
- No need for MRF regions if you are also using rotating walls for wheels. Make sure to delete the Advanced concepts, and include all of the faces of each wheel in the respective Rotating wall sets.
- Try using the standard mesher like indicated in the tutorial, with the Automatic boundary layer option activated. To learn more about appropriate boundary layer sizing, have a look here: What is y+ (yplus)?
Please give these a try, and we can check the convergence and values again after the run is finished, what do you think?
Best regards,
Fillia
