"Simulation assignment on the geometry is not supported for the currently selected mesh"

Hi,

Some notes:

  • The “Simulation assignment on the geometry is not supported for the currently selected mesh. Try to regenerate your mesh or use the mesh as simulation domain.” warning message is shown whenever the background mesh box intersects with the flow domain. It’s just a warning message and it doesn’t mean the mesh is invalid.

If the mesh looks like you would expect, simply click on the “Use mesh as domain” button:

  • The warning message is being shown because the car is currently out of the mesh area:

Is this intended? With the current settings, you won’t have any representation of the car because it’s being left out of the background mesh box. If that’s not intended, I’d suggest adjusting the background mesh box dimensions, so that it envelops the entire flow region.

Hope it makes sense!

Cheers
