Afternoon,
I am working on a project looking at designing an aerodynamic surface for a record attempt and have just started looking into CFD. I have a model but I am struggling to get the meshing operation to work accurately. The only way I can get my model to mesh at the moment and it only works when using the Hex-dominant meshing method. When using this and two mesh refinement areas I am getting poor meshing around the wheels that is connecting them to the body. Is there anyway of making the mesh more accurate in this area?
Also when I mesh the model with a more accurate mesh (very fine rather than fine) it makes the simulation much more unstable.
Thanks
