Hello everyone, I am trying to get CFD analysis for my Formula Student team started. I visited a course held by Ansys on CFD with Fluent meshing and Fluent, but unfortunately they didn't talk about CAD import to meshing. My problem is:

I want to import a simple airfoil geometry (for starters, as I get the same problems with bigger wing assemblies) and simulate it. But I fail at the surface mesh. I take the CAD geometry made in Solidworks and import it to DesignModeler, there build an enclosure and subtract the wing to get the fluid volume, and then import it to Fluent Meshing. Using CAD faceting for the import, I get the following horribly skewed surface mesh:


Using CFD-type faceting with min size = 0.01, max size = 1 and a default curvature angle of 10, I get this mesh:

The triangles are looking good, but there are some missing at tip and end of the wing. If I set a smaller minimum size (f.e. 0.005 instead of 0.01), conformal tesselation fails on the wing area.

So my question is: Is there a way to get a proper surface mesh to use with this very simple problem? I don't want to imagine what problems I will encounter when I get to import the whole car...

Thanks in advance!

Kind regards, Lukas
