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?
Yes, the order of cells of DoFHandlers follows the order of the triangulation.
So two DoFHandlers using the same triangulation have the same order of cells.
step-31, for example, uses this fact.
