Scalable Mesh Coupling for Atmospheric Wave Simulation
Hannes Brandt, Tim Griesbach, Matthew Zettergren +4
We describe the application of a scalable algorithm for interpolating solution data in the overlapping mesh region of two solvers. This feature is essential to obtain a globally co…

Scalable overset computation between a forest-of-octrees- and an arbitrary distributed parallel mesh
Hannes Brandt, Carsten Burstedde
We introduce an algorithm that performs a one-directional mesh overset of a parallel forest of octrees with another distributed mesh of unrelated partition. The forest mesh consist…

A Fast Direct Solver for Elliptic PDEs on a Hierarchy of Adaptively Refined Quadtrees
Damyn Chipman, Donna Calhoun, Carsten Burstedde
We describe a fast, direct solver for elliptic partial differential equations on a two-dimensional hierarchy of adaptively refined, Cartesian meshes. Our solver, inspired by the Hi…
