Dear Friends,
I have modeled a 3D domain using salome. One of the face of model was "partitioned" into two for providing different boundary conditions at two face. Mesh was generated and faces where grouped using "create groups from geometry". Later mesh was exported to unv. while trying to convert the file to OF format it is giving error

ideasUnvToFoam:  ideasUnvToFoam.C:1273: int main(int, char**): Assertion `noveau > -1'  failed.

Code is as follows

where inlet is one of the group which contains partioned face.
when i remove this group from mesh module, the conversion is working fine.
To solve my problem i want that group of face. How to solve this problem.

Thank You in advance
