Beginner's question:
I have created the STL- geom and imported it by using snappyHexMesh.
sHM worked well, but how do I get the boundary conditions to OpenFoam?

=> I used DISCRETIZER, but that didn't work very well.

If you use discretizer-setup.
After you created the snappyHexMesh. Reload that mesh and then choos a solver (simpleFoam etc).
Now you can create BC:s.

Hi Jörg,

You should be able to find a list of faces etc in constant/polyMesh/boundary. Then, using these names, you can define the BC's in 0/U 0/p etc.

You can have a look:

last video shows an example of applying BC:s

Thank you Björn and gwierink (what ever that means)!!!
Morning has broken and sim got runnin'.
YaYaYa!!!

Thanks for discretizer! Nice tool - but manual is needed!

(Steps were: Geom in Pro/E=> STL with Pro/E => Editing STL manually (separating inlet/outlet faces) => creating mesh under DISCRETIZER with snappyHexmesh => creating BCs with DISCRETIZER => starting and viewing sim)

I'm setting up an external aero case as a tutorial.
