Hey everyone,

I want to use OpenFOAM to solve an internal flow in a rectangular duct with circular outlets. I don't really know what is the best way to set the geometry and create the mesh. Do I have to set all the vertices (and the inlet and outlet patches) in the blockMeshDict ? How is it possible to create circular patches then ?
I tried to draw the system with Blender and use the snappyHexMesh tool, but it seems that I still need to set the inlet and outlet patches in blockMeshDict. Anyone knows of a simple way to set up the geometry ?

Another question : what program do you use to open and edit stl files ?

Read the User Guide, the tutorial about stress analysis, plate with a hole.
The key word arc, the starting point, the end point and a third point on the circumference and that is all
Good Luck
