Viewing gauss point information in cmgui

This is a note for someone who might be trying to visualise gauss point stress/strain or strain invariants....

I wanted to visualise gauss point stresses and strains in cmgui to look at their distribution through the body I was deforming.

So in cm I go:

  fem update gauss stress
  fem export gauss;stress yg as stress
  fem update gauss strain
  fem export gauss;strain yg as strain

Now you can read these two exdata files into cmgui and use the spectrum option to visualise the data. I found that I screw up the data range on the spectrum editor if I accidentally choose to use the spectrum for both datasets at the same time. When you click Auto arrange on the spectrum editor, I get the wrong range. So, when I delete one of the data groups from memory, I thought that the range would become ok. But it didn't. My immediate solution to the problem is to just load one data set at a time.

The autorange ranges on whatever is visible and using that spectrum.

The better answer is to make two spectrums (gfx create spectrum data1), one for each set of data. Then you can autorange each one.
