Problem with RBE3 in Hyperworks
Hi, i´m working in a analysis in Hyperworks using the Optistruct as a solver
I need to use a remote force in this point beside the geometry and my ideia is to connect the point and the holes with rbe3 elemments, but i´m having these messages
and idk how to proceed, i would like to fix this errors
thank you

Hi Guilherme,
the solver will error out a message in your case, because your RBE3 needs at least 3 "legs", and non-colinear.
As a very simple example, you can thing about a simple chair where you're going to sit. If there is on 2 legs, it won't keep stable. If you have 3 legs it will be more stable, but if all of them are aligned, then, you loose stability again.
Maybe you could just create a single RBE3 connecting directly the nodes in your holes, instead of adding 3 different ones.
Hi Adriano,
I was trying to fix the errors, but it still occurs that the elements are colinear
The dependent node is the node i will aply the force and the independents are in the holes
Is it possible to make it non colinear?
thanks for the help
