I just added stress plotting to systems_of_equations_ex6. I used CONSTANT MONOMIALs, as you suggested Derek, and plot the 9 entries of \sigma as well as the von Mises stress. David On 06/24/2012 07:35 PM, Derek Gaston wrote: > Lot's of options here... but what we generally do is compute the _a

It seems that the problem was due to unused nodes which didn't belong to any element. mesh.prepare_for_use(false); Solves the problem in some way, since it jettisons those nodes. I'm going to need to solve the problem of matching those soln values back to my original nodes. Thanks Onur Onur 201
