Hello, I plan to test the converge of polynomial multigrid preconditioning on a problem, with matrix-based framework. However, step-75 is a bit confusing since I cannot clearly separate classses contributed by matrix-free and p-multigrid.
Specifically, in step-16 (with MeshWorker) and step-56 (assemble cell_matrix by hand) there are assemble_system() and assemble_multigrid(), while in step-75 there are solve_system() which calls solve_with_gmg and mg_solve. It is due to matrix-free or p-multigrid? By the way, is there a code gallery for matrix-based polynomial-multigrid ?
