Hey Kyunghoon, If you are using FEMSystem, see element_postprocess.C and side_postprocess.C in this example: libmesh/examples/adjoints/adjoints_ex1 ( http://libmesh.sourceforge.net/adjoints_ex1.php) If you are not using FEMSystem, I believe all you will have to do is to wri

Hi all, I wonder what is the best way of computing strain and stress values with displacements obtained by solving linear elasticity problems. I can simply follow displacement-strain and strain-stress relationships (using finite difference to compute gradients), but I guess it would be more natur
