Thank you for your answer, I could make it work.

Hermes,
do you think you could come up with a small, self-contained

Hi Hermes,
I have extended the documentation a bit.
See https://github.com/dealii/dealii/pull/12714.
Maybe you could give us a short feedback if `VectorTools::point_values()`
is working for complex numbers. If this is not the case, we can extend the
function for this use case.

You need to pass a vector of points.

Thank you.
Doing something similar:
*const* MappingQ1 mapping;
Utilities::MPI::RemotePointEvaluation evaluation_cache;
VectorTools::point_values(mapping, dof_handler,
locally_relevant_solution, Point<2>(0.2, 0.2), evaluation_cache);
I get the following error:

Hi Hermes,
You don't need to do anything regarding the setup (it is done within the
function). Just take at a look
at:

Thank you for pointing that function.
I am having some problems when creating the mapping and I am not sure if

Dear Hermes,
Did you try VectorTools::point_values,
https://www.dealii.org/current/doxygen/deal.II/namespaceVectorTools.html#a1ad6eceb6cbeaa505baf7f938289bbde
?
As an alternative, you can also check if the point is in the locally
owned cell of the respective cell, and run the evaluation
Dear all,
I am trying to extend my implementation with parallel computing. I would
like to get the solution in a single point when having a distributed
system. For example, in step-40 I have the *locally_relevant_solution* at
the output_result(...) function.
In a non distributed implementation I

Another thing: You probably also need to initialise with the right number of
components. So something like
Vector vecSol (fe.n_components());

Hi Hermes,
You don’t say what errors you’re seeing, but my guess is that it now doesn’t
compile. This variant of the function (the one that Daniel linked to) returns
void, so you should call it before outputting the result:
Vector vecSol;
VectorTools::point_value(dof_handler,
Thank you for your answer. I am not sure if I fully understand your
suggestion. Do you mean something like that:
Vector<*double*> vecSol;
std::cout << "Solution at (0.2,0.2): "<<
VectorTools::point_value(dof_handler, solution,Point<2>(0.2, 0.2),vecSol)<<
std::endl;
I still get some errors.
Hermes,
Use another overload. The one returning the solution as a parameter should
work:

Dear all,
It is explained in Step-3 how to evaluate the solution in a point. I am
trying to do the same for Step-29, to evaluate the real and imaginary parts
separately in a single point:
*std::cout << "Solution at (0.2,0.2): "<<
VectorTools::point_value(dof_handler, solution,Point<2>(0.2,
