Would you recommend making it flat, so there's a defined edge between it and the remaining foil surfaces? On a side note, what CAD software do you use...

I just put up a test case, which meshes a 3D airfoil, creating a boundary layer, at https://github.com/petebachant/foilInBox-cfMesh. As you can see, the...

I ended up getting cartesianMesh to create an okay mesh by combining my device (vertical axis turbine) and an STL of a box-like domain using MeshLab. I then used surfaceFeatureEdge to extract the...

I just started playing around with cfMesh myself. It looks like the procedure is a bit different, i.e., all geometry (including patch names) goes in a single file (*.fms preferred?), rather than...

I am having reasonable success with snappy these days. It's very sensitive to its input parameters, the background mesh, etc., however, so I may not be able to do a grid dependence study... because I...

Do you have any good resources for this?

You can try refining the background mesh, and turning up the refinement at the fan surface. I've never been able to add more than 20 layers, and that's rare. 12--16 is more reasonable. I keep...
