Shells with surface regions
Shells with surface regions
(OP)
I am trying to model a thin strip of metal that angled about 45 degrees from horizontal. It is loaded along the top long edge, and is constrained at intervals along the bottom long edge. I am trying to see how the metal bows out at the ares where it is not constrained. I created surface regions in Pro/Mechanica (Wildfire integrated mode) along the bottom edge to define my interval constraint regions. I compressed the two large faces to create my shells. When I try to run the model, I get an error message stating that the constraints applied on the surface regions will be deleted. This has something to do with the surfaces being compressed. I have also tried the problem with edge loads/constraints and have the same problems.
Does anyone have experience with shells and surface regions?

RE: Shells with surface regions
I guess you could run this model with solids if it continues to be a problem
RE: Shells with surface regions
If the constraints are full (no translation or rotation) the analysis works fine. However when I allow a degree of freedom (in either translation or rotation) I get the message that the constraints will be deleted.
When I created the surface region, I'm pretty sure that I split the whole surface. How do you determine that?
I realize that I can run the problem with solid elements, but shells seem more applicable to the problem.
