Hello, I am new here.

I am studying mixing in pipe (called mixers in industry), and I wan to generate mesh for a CFD software like OpenFOAM. Within the pipe, there are a series of 2 or 3 turbulent grids -- essentially vertical and horizontal bars in a plane that block the flow and generate turbulence, and there is a high degree of symmetry.

Is there an open-source library of meshes for this kind of geometry which I could use? Otherwise, what is a good mesh generating software that produce such a mesh?

Thank you,
Nadeem

No there are no mesh libraries. OpenFOAM has a mesher. Use it.
