Thank you very much for your answer. Is it then not possible to use somehow
the DataOut approach presented in step-29 and use a 'txt' parameter in the
.prm file?
That's the wrong question. VTK and VTU files are text files, you can open them
with an editor. The question is not whether it's a text file or a binary file,
but what's in it. As I mentioned, the right question is what you want to do
with the information in the file, and depending on that, you choose a file format.
In case of doing that manually as you suggested, how could I access the real
and imaginary parts in the solution vector (step-29)?
Doing something like:
ofstream myfile;
myfile.open ("solution.txt");
myfile << "Point:\t" <<
VectorTools::point_value(dof_handler,solution,Point<2>(1./3, 1./3));
myfile.close();
I get an error when running:
dof.get_fe(0).n_components() == 1
Thank you again for the help.
You are solving a problem that has more than one component -- the real and
imaginary parts are separate components. You need to call that variation of
the VectorTools::point_value() function that returns its information in the
form of a Vector<double> object.
