I have a parameter of type Tensor<1, dim> for each active cell in the

1, Vectors in deal.II do not accept tensor elements.

3, I tried using DataComponentInterpretation, but I am really confused in
implementing it correctly.
I would appreciate it if you could send me an example of writing an output of
type Tensor for each cell. Let's say I have a
std::vector> output;
, and in this vector I've stored the output parameter in each cell using
cell->global_active_cell_index().
Yes, this doesn't work. Just create Vector objects for each component
of the tensor and put things in there.
(Alternatively, if you like a challenge: Write a class derived from
DataPostprocessorTensor in which you just ignore whatever it gets as output,
and instead proceed to use as output whatever you query from your
std::vector> using the cell the evaluate_* function gets as
argument in the input object.)
