Dear Wolfgang,
I do compute the solution at many points along the profile, and while Ex and Ey
look reasonable, the Ez does not. Is it possible that there is a problem in
point_value function for z component for Nedelec elements?

2) For the file with the solution values at the receiver locations I think I
followed the approach implemented in ASPECT.
So I go through all the receivers look for the point value and then check how
many processors found this point and if more
Dear Wolfgang,
Thank you for your replies.
I am still struggling with outputs of the solution to the file.
I have two type of outputs: 1) output vtu files for each processor on the
whole mesh and 2) creating a simple txt file with values of the solution at
receiver locations
1) For the first
Anna,
to compute values of the electric field at the receivers I follow the strategy
of ASPECT code as you suggested
To do this I sum the current_point_values across processors and divide by the
number of processors that contain point p as following
// Reduce all collected values into local

Dear Wolfgang,
thank you very much for the link. I have followed their approach, but
before I can check the result, I have to substitute the solver I used for a
parallel solver.

Anna,
Yes I would like to create a LA::MPI::BlockVector solution_at_receiver. And
then copy it to a
BlockVector localized_solution_at_receiver(solution_at_receiver)
And output localized_solution_at_receiver only on the 0 processor.
I am having trouble initializing and filling

Dear All,
I am not fluent with C++ and MPI and would very much appreciate your help.
I am now following steps 40 and 55 to write parallel implementation of the
solution of the system of Maxwell's equations and am having many questions,
but let us start with the following:
