square external flow mesh generation
 
3 Attachment(s)
Hello fellow Foamers:

I am trying to develop a mesh for a small cube inside a large control volume to analyze the turbulence and vortex generation behind the cube. For starters I am setting the z-direction as empty (2D). Please take a look at my attached blockMeshDict, boundary, and checkMesh response. I do not understand why I can generate the blockMesh, but I am failing 4 of the checkMesh criteria. I used mergePatchPairs to subtract the small cube from the large control volume. When viewing the mesh in ParaFoam/ParaView it looks perfect, cube is subtracted from rest of internal mesh. I am using PisoFoam (LES) as a solver and it won't get past the first iteration.


any advice would be extremely helpful, thank you
