Hey all just an FYI..

If you are using Salome to create your geometry. (CAElinux is a live dvd with salome installed if you want to try it out)

You have the option to explode your geometry into faces give them names like vel_inlet press_outlet etc.. and export each face to their own .stl file.

exporting to an ASCII .stl will allow you to edit the text and give each solid names.

You can then use these multiple files in snappyHexMesh (haven't tried this so don't know if it handles multiple files).

The other way is to combine the face .stl files into a fully defined solid by appending each separate .stl file into one by for example using a command like this. (assuming it is a cylinder)

cat inlet.stl >> assembly.stl
cat outlet.stl >> assembly.stl
cat walls.stl >> assembly.stl

Then you have a fully defined solid and provided you have given the three solids names these will be added to your final boundaries file and you can specify the inlet/oulet conditions as usual after running snappyHexMesh.

Hope this helps anyone.
