Dear Yves, Thanks a lot for your reply. I am not sure what you mean there. I have gone through the example and they calculate Von Mises Stress but there is already a function for that. Could you please tell me which physical quantity or expression is being interpolated in that example so that I can use it as a basis for my pressure calculation. It would be really helpful if you would elaborate a bit on the usage and the example for calculating any expression as I am quite new to fem and getfem. Thanks a lot.
