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 9.4, which needs to be configured with both p4est and Trilinos.
