showing maximum stress of multiple load sets in one result window

I have done something like this in the past, using ascii output files, and let Matlab find the maximum principal stress for several different load sets.

What I have done here is extract the maximum principal stress for each node among several load sets, and then I looked up the minimum principal stress for all load sets, so as to obtain the stress range (max S1-minS3) over a load cycle.

This script works for shell elements, the corresponding stress for solid elements reside in different positions in the output files. So for solid elements, you will need to adjust the code somewhat.

If you don't have matlab, you can use GNU Octave, which is free open source. Octave is almost, but not quite 100% compatible with Matlab. Some modifications of the code could be necessary. 

Extract stress range from several load sets....
