A matrix-free ILU realization based on surrogates
Daniel Drzisga, Andreas Wagner, Barbara Wohlmuth
Matrix-free techniques play an increasingly important role in large-scale simulations. Schur complement techniques and massively parallel multigrid solvers for second-order ellipti…
The surrogate matrix methodology: Accelerating isogeometric analysis of waves
Daniel Drzisga, Brendan Keith, Barbara Wohlmuth
The surrogate matrix methodology delivers low-cost approximations of matrices (i.e., surrogate matrices) which are normally computed in Galerkin methods via element-scale quadratur…
The surrogate matrix methodology: Low-cost assembly for isogeometric analysis
Daniel Drzisga, Brendan Keith, Barbara Wohlmuth
A new methodology in isogeometric analysis (IGA) is presented. This methodology delivers low-cost variable-scale approximations (surrogates) of the matrices which IGA conventionall…
