Dear forummembers,

I am trying to run a 2D multi-element airfoil simulation in simpleFoam. Salome is used to build the mesh. I am able to export the mesh to unv and convert it to OpenFOAM using unvToFoam. However, ParaView does not allow me to see the mesh. Also running simpleFoam does not work. Nevertheless the airfoil2D tutorial works like a charm. I am able to run it, see the mesh, and see the results. I get the following output in the terminal:

FOAM exiting

FWIW I have defined most of the surface groups separately. Meaning I have 7 or so groups. Also I have a group defaultFace. I am not sure why. For as far as I know I have not omitted any surfaces when I defined the groups in Salomé. The geometry is exported from CATIA V5 as .stp . The complete domain is already defined.

Is there anything I can try?

Thanks in advance,

Nick

P.S. I am sorry if this is in the wrong forum.
