I am trying to implement a staggered thermal-elastic solver using the
matrix-free multigrid solver approach from step-37. I got an elasticity
solver and a thermal solver working and now I am trying to associate the
two. I have a shared triangulation, with two separate dof_handlers for the
thermal and stress problems. The question I have is when I do the assembly
loop, does the cell refer to the same cell for both the thermal and
elastic problems?
So from step-37, can I just call phi_temp.reinit(cell), and
phi_stress.reinit(cell), and have cell refer to the same physical cell in
the triangulation?
for (unsigned int cell = 0;
cell < system_matrix.get_matrix_free()->n_cell_batches();
++cell)
{
phi.reinit(cell);
for (const unsigned int q : phi.quadrature_point_indices())
phi.submit_value(make_vectorized_array
<https://www.dealii.org/current/doxygen/deal.II/vectorization_8h.html#ad7d7e08942faeecf438c75a254e06cbe><double>(1.0),
q);
phi.integrate(EvaluationFlags::values
<https://www.dealii.org/current/doxygen/deal.II/namespaceEvaluationFlags.html#a9b7c6d689cb76386839d0d13640f59aeaf9825c682f693a6a200094641a0d6a58>
);
phi.distribute_local_to_global(system_rhs);
}
Thanks!
Subramanya.
