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?
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.
Regards,
H
