Hello,

I have used the 8 noded 3d solid element to analyze the structure displacements and stresses. My task is to built a FEM program using MATLAB which will give the structure displacements and stresses. I got the results for the displacements exactly as same as COMSOL simulation. But for the stresses (Normal stresses and Shear stresses) my results is not same. My question, when displacement result is exactly same and is it obvious that stresses result should be also same for COMSOL and MATLAB simulation.

Thanks in advance.
