The largest potential advantage of DMDA is likely the possibility of easily
using geometric multigrid if it is appropriate for the problem (or subproblem
of the problem) you are solving. The second advantage is, this depends on your
PDE and discretization, the simplicity of your code, and w
Hello,
I am trying to understand if I should make the effort to make my code use
structured meshes instead of unstructured ones. My domain is cartesian so
that is the first check for structured meshes. However, the problem size I
am looking at is ~20 million degrees of freedom. My understanding is
