thank you very much. Why is the car so deep down. It looks like our CAD is not at the origin as the boys told me. I need to fix it I’ll try my best. Do I only have to differ between wings tires (MRF) Porous Zone and main body or shall I have to even separate those right away in single parts like flap, main element and endplates?
Do you know by experience whether you can leave the sideboxes open as they are in reality?
is it enough to put less then 1 m/s for velocity in the initial condition?
Update: @pfernandez thanks alot, it works now! you were right, the simulation wanted different assemblies as input data. Now the simulation runs and the residuals look normal.
