Description
A cell in the mesh has a material ID that is not defined in any Material == block in the sediment transport control file and no default material has been specified.
Suggestions
Either add a Material == block for the reported material ID in the sediment transport control file or add a Material == Default block to handle any unspecified material IDs.
