Hallo everybody!

I asked for the same in another post (here: http://www.cfd-online.com/Forums/ope...tml#post405854 ).

I have this problem.
I want to make a simple simulation in a pipe, with the surface imported as .stl file, so using SHM. This is what I've done: I created a background mesh with blockMesh, then I used SHM with the surface imported as .stl file.
OF creates just one patch for my pipe (the surface I imported), one for all of it. So I have a total of 5 patches: 4 for the faces of the background mesh and only one for the pipe. Instead, I'd like to have more of them for the pipe, like inlet, outlet, internal and external surfaces... But i don't know how to do!
Infact, I tried to launch a simulation, with simpleFoam: it works, but of course outside of the pipe, not inside! This because I can give it (in the simplest case) just a velocity, that is the same all around the pipe, on all my unique patch! It is of course unuseful!

My question is: how can I add the other patches? Or what can I do?
Every kind of suggestion is well accepted , thank you!!

Regards,
Claudio
