I made stress analysis for a natural gas metering station. CAESAR II makes a code compliance check for HYD only and it is OK. But the other loadings causes silly results. One of my loading case is:
T=45 C
P:75 bar
pipe: 42"x19.1 mm API5LX65

Dx=-39370.395 mm
Dy= -17.833 mm
Dz=109038.227 mm

And the reamining figures are similar for all results and nodes.

Most of the model (including the above example) is burried pipe.


I checked my units, all configuration setup is default, I have choosen an avarage soil model. I checked every thing.

What am I doing wrong? Please help me....
