Moving Wall, MRF or Sliding Mesh for modelling rotating rim and tyre?

Field85 · March 18, 2016, 07:30

Hi all,

Want to know if there is a preference for what should or should be used with regard to accurately modelling a rotating wheel/s on a car body. The rim is closed (no spokes). Wheel then partial closed off by body fairing. Is there a do and do not for attempting to model such a structure?. Previous experience is rigid body motion(sliding mesh) for turbines in STAR, but not sure if things change if the wheel is solid.

Any input appreciated,

Fields

And?? Does that mean moving wall is what generally used to accurately model a rotating wheel?

Yes. Thats correct. Road is moving wall in this case.
