Hi, I am a student currently doing a thesis on motorcycle aerodynamics. I am very new to any CFD software and have not studied much aerodynamics. I have been teaching myself Star-CCM+ from a meshing tutorial which I was given.


Tomorrow I am going to put a scale motorcycle into a small wind tunnel and take a drag reading through a fixture that screws into a load cell in the wind tunnel floor.

My star-ccm+ is using identical: model size and velocitys. This means that the rod which connects between my bike and load cell goes through the floor of the region. (which was set as a symetry plane)

I made the scale model which I imported as an X_T file. I then tried to fix the model representations - import [right] - repair surface (I then deselect the two bottom check faces)

Problem is - it refuses to surface mesh, the error is as follows:

Worst quality is 5.523e-005
initial number of faces: 66732

starting: Apply Global Limits
Error during surface remeshing, deleting resulting mesh
Parasolid function PK_CURVE_eval_curvature failed.
Error token = PK_ERROR_bad_parameter
Error code = 120

Any thoughts and advice would be brillaint.
