I understand (or more accurately I have followed the examples, such as
its2D_5) how to calculate the stress and strain for an elastic deformation
problem and probe along a line. What I want to do now is display the
surface of the material and color it by one of the (for example) strain
components, such as the zz component of the strain tensor. It seems like
one just has to create a pipeline in mayavi2 that uses the
ExtractTensorComponent filter but for the life of me I can't figure out how
to select a single component (such as the zz one of stress or strain) to
use to create the surface mapping. I can change the scalar mode value
in ExtractTensorComponent from "effective stress" to "component" but I
don't understand how to choose a particular component.
I hate to post what is probably a simple question but lots of searching
hasn't yielded an answer yet.
