I made a microstructured fiber and studied it using RF modeule. I got the the expected resluts using the mesh setting I entered. Now I want to study its response to changing external pressure for which I am using solid mechanics to find normal and sheer stress components. I am using it for the first time so after a research I found that I have to do the stationary study for these components. I used 'Plane stress' under 2D approximation, Fixed constraint, and Boundary load at the external boundary of my structure. Now the problem is I am getting the error: Failed to find a solution. The relative error (0.69) is greater than the relative tolerance. There was a warning message from the linear solver. Iterative refinement triggered. Returned solution is not converged.
These same mesh settings workked for madal analysis of my structure under RF module. Why is it not working now. Maybe I am doing some other mistake. Kindly guide me. Thankyou.
