Handle exception when no library extension is provided in TypicalMaterials file #1
Description
If no library extension is provided for a cross section in Typical Materials, MCNP generates 3 fatal errors. Seems as if it is just unable to find cross-sections, but does assign the library extension by the looks of it?
fatal error. cross-section tables missing for zaid = 33075.31c
fatal error. cross-section tables missing for zaid = 73180.31c
fatal error. Models required. Cannot use memory reduction option.
