Multiple Boundary Condition Assignment Error

I am simulating an F1S car. I have created a mesh for it following the steps given in this tutorial:

This is the error that keeps showing up when I try to simulate.

Thank you!

Hey Manomay,
the issue here is that your “Body” topological entity contains the wheels too.

This means that the No-slip wall condition was assigned to them as well. As a result, the wheels have more than one bc assigned to them (the No-slip wall condition, and the Rotating wall for each wheel).

You can fix this by creating a topological entity set that does not contain the wheels :smiley:
