ENGRID is a mesh generation software with CFD applications in mind. It supports automatic prismatic boundary layer grids for Navier-Stokes simulations and has a Qt based GUI.
I have tried to mesh a propeller blade with engrid. The surface mesh is created outside engrid with gmsh ("bamg" surface mesh algorithm).
I did the steps:
import Gmsh ascii v2
create prism boundary layer (default settings except "stretching factor" which is set to 1.7)
create/improve volume mesh
divide prismatic boundary layer
export OpenFOAM (grid only)
Everything works without errors, but the final mesh contains negative volume cells where the trailing edge hits the hub. The number of problem cells increases, if the "stretching factor" in step 2 is decreased.
Perhaps this case is of interest as testcase for further code development. I put it here: http://kroegeronline.net/exchange/rotor_domain.tgz
I used engrid built from the current commit of the "release-1.4" branch.
