Yes, you can do
Thank you very much for your guidance.
I think that with the H curl conforming element like FeNedelec or
FeNedelecSZ, my solution vector has continuous tangential component, isn't
it?
Thus, Is there some where I can see my vector solution is discontinuous?
Can I check it by visualization?
I think

I highly appreciate all of your answers. It becomes clearly for me to look
through the library.
Let me show all of my function and my ideas below.
I set the point for evaluating its solution to be on the vertex of a cell,
and using the following function to get the solution

Correct.

Dear Pham,
When you use the FEValuesExtractors in conjunction with the FEValues class
using the operator[] like you’ve done here
> fe_values[vector_re]
then what is returned is an FEValuesViews type object. Since your vector_re
extractor is of type FEValuesExtractors::vector, the returned
Thank you very much for your answer.
So for the first function
VectorTools::point_value(dof_handler,solution,point,values);
I can specify the observed point in real coordiante, solution vector and
dof_handler to get the values, right?
For the second one, assuming that I am using QGauss for
