A multigrid reduction framework for domains with symmetries
Àdel Alsalti-Baldellou, Carlo Janna, Xavier Álvarez-Farré +1
Divergence constraints are present in the governing equations of numerous physical phenomena, and they usually lead to a Poisson equation whose solution represents a bottleneck in…
