Hello fellow Foamists!
You have been most helpful so far. I really like this forum. Let's say I have an STL file with two pipes that are modeled as cylinders, and they can be intersecting or abutting. Please see attached image. I would like to model internal flow through the pipe. I have the outlet and inlet defined as the big circle and the small circle on the other side. SnappyHexMesh meshes only one of the cylinders. Is there a way to make it mesh inside the entire outer surface and ignore internal faces? Probably too much to ask, eh ? I currently don't have a way to remove the offending faces from the STL file.

Hi Mihai,
Check the tutorial "mesh/snappyHexMesh/snappyMultiRegionHeater". But keep in mind that this means that you'll have multiple regions in you mesh! Some examples on this subject:
Best regards, Bruno

Thanks Bruno, I will check those out. I figured getting rid of the patches would be the main issue...
