SalomeToOpenFoam

when I use the Script SalomeToOpenFoam.py convert Meshes to OpenFoam,it shows the following Errors.How I can solve these Problems?

The error says it, you have a face that is shared by more than one 2d group. Correct this so each face is only in one group

Thank you for your help.How I can find the elemId 1142 and solve this problem?

I imagine that the groups of the mesh, from groups made in the geometry, it is there where you need to check that one of your groups share some faces with the inlet group edit that and re create your mesh.
