RBE3-elements

Hi,

 

I want to contrain a model, but to make sure that the effect of the constraints, don't influence the values. I'm trying to use an RBE3-element. This would spread the effect of the constraint and decrease high stress concentrations.

 

However when I try to constrain the RBE3- elements in their dependent node, I get an error message explaining that there are conflicts with the dofs for the RBE3-elements.

Is there a way to solve this problem?

 

Kind regards

    Try making a cbush at dependent node and give a high stiffness to pbush

    That's Solver dependent in fact.

    With SAMCEF solver for example I can apply constrain directly at dependent node of RBE3.
