Dear all,

I am trying to simulate a pipe flow where a fan drives the flow. The fan is located half way down the pipe. I was running the fan bc tutorial (http://www.tfd.chalmers.se/~hani/kur...010/fan.tar.gz) succesfully. There the mesh is generated just by blockMesh. However, the geometry of my pipe is a bit more complex so I need to generate the mesh using blockMesh + snappyHexMesh.

Can anyone tell me the workflow for such a problem?
Do I need to mesh the whole geometry, then split it using splitMesh and eventually run createPatch? If this process is the correct process, does anyone have an example for the correct usage of splitMesh and createPatch for such a case?

Thank you!
