Sandbox for hp-adaptive methods

===============================

[![DOI:10.5281/zenodo.6425947](https://zenodo.org/badge/DOI/10.5281/zenodo.6425947.svg)](https://doi.org/10.5281/zenodo.6425947)

This program is used as a benchmark to demonstrate the benefits of

parallelization, hp-adaptive methods and matrix-free methods combined.

All results of the following paper have been generated with this

program.

Dependencies

------------

This program requires a deal.II library built from the current master

branch (version 9.4.0-pre). It needs to be configured with both p4est

and LAPACK.

Further, your deal.II library has to be configured with either PETSc or

Trilinos for algebraic multigrid (AMG) methods. The geometric multigrid

(GMG) implementation currently requires Trilinos and is not compatible

with PETSc.

Compiling and Running

---------------------

To generate a makefile for this code using CMake, create a build

directory to your liking and type the following command into the

terminal from the build directory:

	cmake /path/to/hpbox -DDEAL_II_DIR=/path/to/deal.II

To compile the program with all of the applications, call:

	make

  

An executable named `hprun` will be created. Running the application

will automatically generate a default parameter file in the folder where

the executable is located, and uses the default parameter set for the

current run.

A selection of parameter files for different scenarios is located in the

`examples` folder. In addition, you will also find the parameter files

that were used for data generation in the above mentioned paper.
