Hi Wolfgang,
Thank you for pointing that out. I was wrong because I thought that what
happens with 1-D is the same as in 2-D, and that’s not true.
I will try to think again how I solve the problem and the structures
related to it. Thank you for the suggestions!!
Best

This is not the right approach. DataPostprocess is used to put derived
quantities into output files, not to compute data that can then be used in
other parts of the program. For what you
Hi Jean-Paul and Wolfgang,
Exactly, I would like to use what my DataPostprocessor computes in other

Here my problem:
In my postprocessor, I compute stresses and principal stresses for all
quadrature points (to give you the context, I am using quad elements with 4

These variables are saved on the data_out object, so I use

not know how to access to these new variables (computed_quantities) from

Hi Raul,
The “input_data” argument to the evaluate_vector_field() function has a method
that can be called to retrieve the cell that is currently being processed:
https://dealii.org/developer/doxygen/deal.II/structDataPostprocessorInputs_1_1CommonInputs.html#a2bc88342acd8e41314c8c1328bd98a67
It is not clear to me how to access an object in the structure
“Postprocessor”. The idea is that I compute the solution, but I am also
computing secondary variables using the postprocessor structure in this way:
dealii::DataOut data_out;
data_out.attach_dof_handler(dof_handler);
