I want to find the minimum pull force to pull out a glass shelf from the grip of its clamp. I have used displacement boundary conditions that inserts and retains the glass shelf into and from the clamp, and extracted reaction forces of 230N. <\/p>\n

 <\/p>\n

Now on another analysis, I want to give this 230N force as boundary condition on the glass to pull it out of the clamp. But in this analysis the solution does not converge. Errors suggest to check the model constraints and contacts. Can I have some understanding as to why this happens? I have provided the same contacts and constraints in both analyses, the only difference is that in the first one I had given a displacement to extract reaction force results, and on the second one I want to input a force to extract deformation results. <\/p>\n
