I finally got the 5.2 on my machine now. When I tried to run the WRC 107 analysis, I noticed that in the INPUT ECHO report, the part where internal pressure should be is missing, which should be around the red line.
Could you any one tell me how to fix this? Thank you very much.

ANY COMMENTS ON THIS OLD ISSUE?

There were updates made throughout the life of Version 5.20. In addition, the current version of CAESAR II is 5.30.

My problem is that we are using CAESAR II 5.2 build 100715, and i don't if we are going to upgrade. Meanwhile, how can I overcome this issue?
