Finite Element 3D post-processing

Does anyone know or have a code for graphically displaying the stresses/strains in a 3D finite element mesh? I tried using surf command but it doesn't work.

What data do you have

Hi Darova,

Attached is the script and the files to run it. It's really long. Please check through the function from line 1018-1094. I correctly plotted the displacement (line 1018-1030), and tried to use the same method to plot the stress/strain but their plot is inacurrate. Please have a look and get back to me. Thanks.

Te above shall help......if not attach your data.

Thanks, KSSV, but I already used that to post-process the deformationt results which was given. There was no code for the stress/strain results.

I have attached my code and some files to run with it. Please check through the function from line 1018-1094. I tried to use the same method used to plot the displacement to plot the stress/strain but their plot is inacurrate. Please see if you can tweak it a bit. Thanks.

YOu can do that using this function https://in.mathworks.com/matlabcentral/fileexchange/32719-postprocessing-in-fem

To be honest I can't. I'm new to matlab.

Like I said, the code given there was to plot only the deformation and not the stress/strain. I have plotted the deformation correctly but don't know how to plot the stress/strain because it wasn't given. If you can look at the line 1018-1094 of my code you might be able to help. Thanks.
