Rigid Beam Problem

Rigid Beam Problem

Rigid Beam Problem

(OP)
Hi all first post so hope you can help!

I am trying to model the effect of applying a force at one end of a rigid beam, on the displacement at the other end which in turn is connected to a piece of plate (representing a flat bar stiffener). The rigid beam is constrained at a point between the two ends so that is can only rotate.

So in theory, the force at end 1, should cause a rotation about a mid-point and therefore force a moment at end 2 onto the stiffener.

There may be a better way to model this but I am currently attempting to use an MPC184 element to model the rigid beam and the SHELL181 element to model the stiffener. I am also using non-linear analysis as advised by ANSYS for MPC184 elements.

At the moment there is no convergence of the solution and no deflection. I would hazard a guess at the fact that this is down to my knowledge (or lack of) about the MPC184 element.

So my question is, how can I setup a MPC184 element to be used in this way?

Thanks for the help!
