Hi everyone!

I'm a newbie to OpenFOAM and I'm facing a problem when trying to run one of my first cases.

Basically what I'm aiming to do is to simulate the flow inside a curved channel. I created the CAD geometry with Inventor then exporting it in a .stl file.

I managed to mesh inside my channel using sHM but now I would like to apply boundaries conditions to it, basically a velocity inlet and oulet and the rest of the channel faces should be walls, so I could finally execute simpleFoam on my case.

But I don't know how I'm supposed to select the good faces to create the inlet and outlet patches.
And sHM created 32770 patches, called channel_patch0 etc. until channel_patch32768...

Any ideas?

Cheers
