Quasi-matrix-free hybrid multigrid on dynamically adaptive Cartesian grids
(2018)
Journal Article
We present a family of spacetree-based multigrid realizations using the tree’s multiscale nature to derive coarse grids. They align with matrix-free geometric multigrid solvers as they never assemble the system matrices, which is cumbersome for dynam...
