Convergence on a CFD car model


It’s my first CFD study and particulary for a car. I just design this for the test and understand the internal flow in the car and interaction between external and internal aerodynamics.

I did some test with differents mesh sizes and times steps for the solver but i’m not sure that my results are corrects (results are stranges…).
Is someone able to have a look on my model and give me some tips for the right size of meshing , numerics and simulation control parameters ?


I have a feeling this is the same issue that happened in this thread. Can you give it a go with potential foam initialization enabled? That’s probably going to fix the issues.

Thanks for the tip. Effectively it looks similar. I test now and give some news asap.
