I have read that to see if a material model is stable/unstable, you can plot the contour plot of strain energy density function. And it should looks like this in the rapport

If it is one local minimum it is stable (picture to the left) with more unstable (picture to the right).

The result I get in Ansys with that command you gave me

So is there another way to get the contour plot? Have I undetstand wrong?
