So I suppose the reason I was getting crappy results with the airfoil at low angles of attack was because I was specifying the boundaries of the control volume incorrectly. The flow around the...

In order to use blockmesh, if I'm right, you need to have the vertices of the volume already defined, including patches, blocks, edges, etc. If there is a trivial way of doing this for an airfoil,...

NGSolve airfoil mesh

Hi,
I've been getting pretty crappy results with an airfoil at a small angle of attack in openfoam, I'm using NGSolve to generate the mesh (which doesn't look very nice) and gmsh to optimize it and...

Thanks Henrik,
If I want to analyze my own airfoil, I would still need to write a blockMeshDict file to generate the boundaries, cells, faces, etc. data.
If so, how would I set up the vertices,...

Do I need to create one,...
