Please guide me,
I am solving a non-linear static structural problem, which consists of several components. I have imposed displacements at certain nodes connected by rigid beams. After solution I extracted the nodal force and moment data for those nodes using PRNLD,F,,ALL & PRNLD,M,,ALL command. Now using the values of forces and moments I imposed force BC to solve the same. But facing convergence issues (mainly contact problems). I have tried using FSUM command also, but it doesn't give accurate moment because of large rotation.
Is there any efficient way of solving the issue?
It is quite confusing and so that difficult to answer to your question Mr. Bhrigu K Lahkar , but as per I have understood you may get help to solve your problem... please refer the given link @Bhrigu K Lahkar

Have you tried resolving the contact issues by measures like increasing the number of substeps?
