The deal.II tutorial step-75: parallel hp-adaptive multigrid methods for the Laplace equation

  • 1. Colorado State University
  • 2. Technical University of Munich, Helmholtz-Zentrum hereon

Description

The tutorial demonstrates how to apply hp-adaptive finite element methods efficiently on thousands of processes with distributed memory access. We make use of a hybrid geometric multigrid approach combined with matrix-free methods.

This version requires a deal.II library of version 9.3, which needs to be configured with both p4est and Trilinos.
