Audrey,
I'm trying to export data as tensors to vtu format (for ParaView) with the
add_data_vector() function with
DataComponentInterpretation::component_is_part_of_vector.
Did you mean to say "...is_part_of_tensor" here?
The vector case is discussed in step-22. There is no current example for
tensors, but you could take a look at this test:
https://github.com/dealii/dealii/blob/master/tests/data_out/data_out_12.cc
Unfortunately, I don't know how to use it properly and I don't find any
example or clue about it in the deal.II documentation or on the GitHub page.
There's one Reynolds tensor per node and they are stored in a vector. Since
the number of components (4 or 9/node) is bigger than the number of dofs (3 or
4/node) or the number of cells, I always got an error.
The number of DoFs per node is not related to the interpretation of things.
What matters is that you need to have dim^2 components of your vector-valued
finite element marked as tensors.
What is the specific error message, and what is the piece of code with which
you try? It might be easiest if you showed us the code and the error message :-)
Best
W.
