Assembly mesh intersection

When I mesh the assembly file of my car, that is, 4 wheels and the body part, mesh is created at both the surfaces where the parts are mated and so the mesh shows intersections. I tried removing the 2 mated surfaces when I mesh them with QI but that did not help with the simulations since intersections do not eliminate. What can I do?

I then simulated the car with creating a single part with the wheels being extruded cylinder and performed my sims without rotating wheels.

Could you let us know the which solver & what type of analysis you are running?To overcome intersection issue we have option in Hypermesh.

I use VWT which uses AcuSolve as solver and I run Steady State analysis with a course meshing status.

Thanks for the update. I will let CFD experts to comment.

Nope, I guess it's a hypermesh problem. How can I exclude the mated surfaces and remove the so called-intersections in the 2D mesh created?

Could share some snapshot of your model where you are facing problem?

See the intersections on the LHS. When I drew a required circle on a wheel and excluded the 2 surfs which mated then still I got some intersections which I don't know how to resolve. Kindly help me!
