[Paraview] Fwd: Question about strain from filter: Compute Derivatives -> Vector -> Strain.... type?

[Andy Bauer]

I believe that it is just computing the gradient of a tensor and doesn't
assume what the actual tensor quantity corresponds to. Thus I would assume
an infinitesimal strain type of computation.
