Conversion from CAD to stl file
 

Hi All,
I have created a CAD file with FreeCAD and now I would like to "convert" it into .stl format (and I want also to define regions of my geometry) in order to use that in snappyHexMesh, but I am not able to do that. Could anyone know how to proceed, please?


My objective is to generate a mesh based on a specific geometry (i.e. a convergent-divergent nozzle), so I do not have to follow this strategy. If anyone knows a better way to do this (e.g. gmsh, salome, or others), I am open to suggestions.
Pardon me if this is a trivial question.
Thanks in advance,


Tommy
