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…

A Scalable and Modular Software Architecture for Finite Elements on Hierarchical Hybrid Grids
Nils Kohl, Dominik Thönnes, Daniel Drzisga +2
In this article, a new generic higher-order finite-element framework for massively parallel simulations is presented. The modular software architecture is carefully designed to exp…
