@fredrik would like to introduce automatic naming of tensor components:

See this discussion:

And this MR:

https://gitlab.kitware.com/paraview/paraview/-/merge_requests/5442

There is already automatic naming of 6 component symmetric tensor like this:

`"XX", "YY", "ZZ", "XY", "YZ", "XZ"`

But it appears that there is no such standard for 9 component tensor, and that even this 6 component mapping could also be considered without any standard.

For 9 components, there is two suggestions:

`XX XY XZ YX YY YZ ZX ZY ZZ`

`"XX", "YY", "ZZ", "XY", "YZ", "XZ", "YX", "ZY", "ZX"`

Does anyone have any inputs on this ?
