Description
A material definition references a group index that exceeds the number of material groups defined in the mesh file. The number of material groups is set in the .2dm file and determines the valid range for Material Group ==.
Suggestions
Check the Material Group == value in the sediment transport control file and ensure it does not exceed the number of material groups encoded in the .2dm mesh file.
