Hello,


It seems like you are using the following boundary conditions to solve the problem. The direction of your velocity inlet BC is also consistent with this. These seem incorrect.



Please flip these boundary conditions. Use Velocity inlet on the front face (near the front side of the car) and pressure outlet near the backside. Also, change the 'Velocity Specification Method' to 'Magnitude, Normal to Boundary'. This should help your simulation.



Hope this helps.


Best Regards,


Karthik
