Abstract

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 exploit the
resources of modern and future supercomputers. Combining an unstructured topology with
structured grid refinement facilitates high geometric adaptability and matrix-free multigrid
implementations with excellent performance. Different abstraction levels and fully distributed
data structures additionally ensure high flexibility, extensibility, and scalability. The software
concepts support sophisticated load balancing and flexibly combining finite element spaces.
Example scenarios with coupled systems of PDEs show the applicability of the concepts to
performing geophysical simulations.
