The expansion coefficient data that we have for that material runs from 21 degC to 426 degC. If you have a temperature value (either ambient or Tx)anywhere in the job outside of that range, you'll encounter the above error.

Note that we only have an entry for this material for B31.3, and the generic "All Codes". If you're using B31.3, then you would have to extend the data for the B31.3 entry, otherwise extend the data for the "All Codes" entry.

If you can't get this to work, send (to Tech Support at "caesarii@intergraph.com" your "umat1.bin" file and your job file (.c 2).
