EXAHD - A massively parallel fault tolerant sparse grid approach for high-dimensional turbulent plasma simulations
Lago, Rafael; Obersteiner, Michael; Pollinger, Theresa; Rentrop, Johannes; Bungartz, Hans-Joachim; Dannert, Tilman; Griebel, Michael; Jenko, Frank; Pflüger, Dirk (2020-03)Plasma fusion is one of the promising candidates for an emission-free energy source and is heavily investigated with high-resolution numerical simulations. Unfortunately, these simulations suffer from the curse of ... -
A mass-conserving sparse grid combination technique with biorthogonal hierarchical basis functions for kinetic simulations
Pollinger, Theresa; Rentrop, Johannes; Pflüger, Dirk; Kormann, Katharina (2022-09)The exact numerical simulation of plasma turbulence is one of the assets and challenges in fusion research. For grid-based solvers, sufficiently fine resolutions are often unattainable due to the curse of dimensionality. ...
