MURPHY -- A scalable multiresolution framework for scientific computing on 3D block-structured collocated grids
Thomas Gillis, Wim M. van Rees
We present the derivation, implementation, and analysis of a multiresolution adaptive grid framework for numerical simulations on octree-based 3D block-structured collocated grids…
