I need some help with setting analysis conditions in ansys workbench. I'd like to make analysis on beam, according to the attached drawing.
I need information what is the best way in ANSYS Wb to make this kind of supports (I choosed Remote Displacement and blocked all translations and rotations) and how to make beam, marked as AB nondeformable (another three beams are deformable). I created my four beams in SpaceClaim (Split Body) and set ShareTopology as "Merge", but then I had problem with Contacts when i assigned Stifness Behaviour as Rigid. Could you explain me what will be the best solutions for both problems?

You can use a 184 type of Element for rigid beam. See how this is done within workbench below. It only takes nodal loads. If distributed loads then use normal beam with a higher e Modulus say 10 or 10000 times higher. Do a study to see that the stresses on the other beams are not influenced by doubling your e Modulus. Say to go from 10000 to 20000 times higher does not change results.

Thank You very much, can You say something about supports? How to imitate this kind of support in ANSYS Workbench?

Thank you jj77. I created lines from points, added cross sections and applied supports in points (fixed supports, according to drawing -> applied in points, because I used beam elements) and it does not work. "There is at least 1 small equation solver pivot term (e.g., at the UY degree of freedom of node 34). Please check for an insufficiently constrained model".
ANSYS can't find solution, I suppose i have to find a diffrent way. I will appreciate any suggestions.
