This is my first foray into using CaesarII. I have used another program previously.

I am using B31.5 and analyzing A53B pipe.

The temperatures I am using are 125F and -45F.

Pressures are 340 and 45 psi, respectively.

When I select the Allowable Stress, SH2 comes in at 0.0 psi, while SC and the other SH values propagate at 17100 psi.

Sy enters at 35000 psi.

This yields a Warning number 121E for each entity.

I also get a Warning number 134E for each entity.

I can change the SH2 value manually to 17100 psi and eliminate the 121E warning, but that is inconvenient.

Any ideas or comments?

Thanks in advance.
