I am working on a project with a Titnium B862 spec and can't find it in the Materials list in Caesar. Is my client wrong in assuming that tihs is still on the list, or is this missing from the databasa?

The CAESAR I material database does not hold all the materials that a specific piping code mentions. You can always add materials to YOUR database. If it's a one-off material, you can also set the material to "user defined" and explicitly enter all the required data for that specific model/analysis.

Thanks David, I was not aware that the material list in Caesar did not include all the specs, and of course this one is rare as it it the first time I have had ti work with it in my 15 years of carrying out PSA's.
