Hello everyone.
I want to extract the element solution vector from the global solution once
the problem is solved in step-40. For a serial code, I would do something
like this:
*int i=0;*
*for (const auto vertex : cell->vertex_indices()) { int a =
(cell->vertex_dof_index(vertex, 0)); element_sol[i] = solution_vector[a];*
* i=i+1; }*
I don't have a solution_vector for a parallel code, but a
locally_relevant_solution. I want to know that, given this
locally_relevant_solution and the cell, how do I get the element_sol?
The global_dof will not be helpful here, as the solution_vector is
distributed across a number of processors.
Thanks and regards
Wasim
