Solving Method

In CAESAR documents have written solving method of CAESAR II is Finite Element. But when I model a straight pipe between two anhors in CAESAR and ANSYS results are different. why?
For example in CAESAR pressure elongation and shrinking of the pipe due to internal pressure is ignored(for B31.3) but in Finite Element programs these are considered. what is commentary?

RE: Solving Method

Also, Which data of CAESAR results are based on finite element and which are based specified code?(Stress??? restraint loads??? displacements???)

RE: Solving Method

I don't mean to jump ahead of Rich Ay and colleagues at Intergraph / Coade, but they seem to have missed this question.

You can specify whether or not pressure elongation is considered in a Caesar II analysis to B31 codes, see Special Execution Parameters.

The FE method used is based on beam theory. Displacements and loads will be classical FE results but stresses are of course Code dependent.


RE: Solving Method

Sorry, we've been very busy.  C2IT is correct.
