Description
A material group number specified in the control file exceeds the number of material groups defined in the geometry file. The material group numbers in the control file must correspond to groups that exist in the mesh.
Suggestions
Check the material group numbers in the Material == blocks of the control file and verify they match the material group IDs defined in the mesh geometry file.
