Thank you for your answer.
Following the examples you mentioned, I got a vtu file where I can extract
the points. As I am using distributed tirangulation, I am getting the (x,y)
values of the points of each cell, meaning that the points are not unique,
there are repeated.
* DataOut<dim> data_out;*
* DataOutBase::VtkFlags flags;*
* flags.write_higher_order_cells = true;*
* data_out.set_flags(flags);*
* data_out.attach_dof_handler(dof_handler);*
* data_out.add_data_vector(solution, "sol");*
* Vector<float> subdomain(triangulation.n_active_cells());*
* for (unsigned int i = 0; i < subdomain.size(); ++i)*
* subdomain(i) = triangulation.locally_owned_subdomain();*
* data_out.add_data_vector(subdomain, "subdomain");*
* data_out.build_patches();*
* data_out.write_vtu_with_pvtu_record("./", "solution", 1,
mpi_communicator, 2, 8);*
I would need to get the unique points corresponding to the domain in the
same order as the operators are assembled. Similar to what I got with
grid_out_write.msh but including the higher order points. COuld you please
suggest me how can I approach that?
Thank you again.
