3-d solid boundary conditions

3-d solid boundary conditions

3-d solid boundary conditions

(OP)
Hello!

I am modeling a concrete structure in Adina where I would like to apply a rotational constraint to a 3-D solid element, which happens to not be one of their degrees of freedom. Since I have constraints already applied to each element (in the form of rebar elements) I cannot assign a master/slave relationship to the 3-d solids. I have worked out a crazy sort-of thing with some beam elements and some stiff shells and it looks okay, but I was wondering if anyone here had any better ideas??

Cheers

Owen

RE: 3-d solid boundary conditions

I haven't used Adina, but you can't apply a rotational constraint because 3-D element formulations are only 3 degree of freedom elements, and all three degrees of freedom are translational.

Can you post an image of what you've done so we can see how you are attempting to restrict rotation with the beams?
