The surrogate matrix methodology: A reference implementation for low-cost assembly in isogeometric analysis
Daniel Drzisga, Brendan Keith, Barbara Wohlmuth
A reference implementation of a new method in isogeometric analysis (IGA) is presented. It delivers low-cost variable-scale approximations (surrogates) of the matrices which IGA co…
Stencil scaling for vector-valued PDEs on hybrid grids with applications to generalized Newtonian fluids
Daniel Drzisga, Ulrich Rüde, Barbara Wohlmuth
Matrix-free finite element implementations for large applications provide an attractive alternative to standard sparse matrix data formats due to the significantly reduced memory c…
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…
The surrogate matrix methodology: a priori error estimation
Daniel Drzisga, Brendan Keith, Barbara Wohlmuth
We give the first mathematically rigorous analysis of an emerging approach to finite element analysis (see, e.g., Bauer et al. [Appl. Numer. Math., 2017]), which we hereby refer to…
