I'm trying to generate a BL around a spinning wheel (on a car), but I can't seem to get it to work. I'm using ANSA for a surface mesher, while I use Tgrid and ANSA as a volume mesher (neither has been able to generate a BL).

The issue is the ground - the prisms won't generate near the ground, with the wheel slightly above the ground or slightly below it, or they will just generate straight through the ground, and the volume mesh will fail.

Does anyone have any advice on avoiding this? Is there a way I can generate the layer taking into account the ground? Can I do a simulation that gets rid of the control volume? I don't know much else outside the realm of finite volume modeling.

I also have ICEM at my disposal, but I'm new to it, so I don't know much about it.
