Beware of pressure directions in axisymmetric models!
In Creo 1.0 they are all messed up for radius and conic curves (not lines). Ergo, if you need your pressure force pointing "outward", then for some curves you must actually direct them "inward"!! The only good news is this: After performing an analysis, turn on the "show loads" option. The post-processor will show you the directions that were used for the solution. Quite the nightmare.
Re: Beware of pressure directions in axisymmetric models!
I believe we have identified this issue and have a fix that will go into Creo 2.0 M090, but I would like to verify it against your model(s), if you can share them. Could you please open a case with Technical Support ?
