Hi @rfensterseifer, I agree some odd results here:
I certainly wouldn’t expect velocities of these extremes (1.3Km/s? in some areas), however your simulation setup looks very reasonable.
So I would look at doing these changes:
- Increase your bounding box. To me it looks like we are getting a bit of interference from the walls… I’d say treble the height and width and maybe double length (behind).
- Add layers to the ground. I know the ground is moving the same velocity as the air however under the car, velocity will increase a lot and therefore will have a boundary layer.
Apart from that I think its a solid setup so beyond this I don’t think I can give any further advice, if this still produces odd results we might need backup
