Hi,
What I'm trying to do is:
- use a single dependent node linked to one or more surfaces with a rigid constraint, to enable a set of displacement constraints (or freedoms, or prescribed displacements) at the dependent node, for use with boundary constraints or guided movements in large deformation nonlinear analysis. The specific application is for calculating plastic force-displacement characteristics.
- the same, but with weighted links, for cases where I don't want to overly constrain components around the constraint
Are either of these things possible in a nonlinear large deformation analysis? What are the workarounds I need to do?
I'm aware of the workaround using a spring or beam for Creo Simulate's limitation of not being able to apply a constraint to the dependent node of a weighted link as described here: Rigid link versus weighted link - PTC Community However I've found that if I try to use a beam or a spring in a nonlinear large deformation analysis it tells me I can't use them, so I'm a bit stuck on how to proceed.
Also a general question. When I'm trying to find information in the documentation about limitations of features with different types of analysis, I can't seem to find anything. So I end up having to find out what options work together by trial and error. Have I overlooked a section in the documentation which explains this stuff? Or is there some trick to navigating the documentation to find detailed explanations of the different features and limitations of their use?
Thanks, Pete.
