Derive required force from prescribed displacement

Please login with a confirmed email address before reporting spam

Hi all,

I am currently doing a study on a leaf flexure subjec to certain boundary conditions. I apply a prescribed displacement in the x-direction on one edge. Now what I would like to do is derive the required force in x-direction if I were to apply a force in stead of a displacement on this edge. I tried to figure this out using the reaction forces tab in plots, derived values and probes, but never did I get a good result. How should I do this? I added my file in the attachment.

Best regards

It sems like you are prescribing the displacement on an edge that is also constrained by a rigid connector. Even if it is intended and non-conflicting, there is no way to separate the reactions.
