A stencil scaling approach for accelerating matrix-free finite element implementations
Simon Bauer, Daniel Drzisga, Marcus Mohr +3
We present a novel approach to fast on-the-fly low order finite element assembly for scalar elliptic partial differential equations of Darcy type with variable coefficients optimiz…

A two-scale approach for efficient on-the-fly operator assembly in massively parallel high performance multigrid codes
Simon Bauer, Marcus Mohr, Ulrich Rüde +3
Matrix-free finite element implementations of massively parallel geometric multigrid save memory and are often significantly faster than implementations using classical sparse matr…
