I understand there is no data component interpretation for tensors (I

that in aspect 1.3 ASPECT 1.3 released.

are "New visualization postprocessors that can output the shear stress
and full stress tensors". Is it a dedicated procedure for vtk?
No. The tensors are output as individual scalar components.
Of course I can manage by projecting tensors on three orthogonal
directions and visualize as vectors, but I find this inelegant.
That's the way to go, unless you want to implement the
DataComponentInterpretation part as well as support in DataOutBase for
tensor-valued quantities.
