Discontinuous Galerkin Finite Element Library and Solvers

Project description

blitzdg

blitzdg is an open-source project aiming to implement parallel discontinuous Galerkin (dg) solvers for common partial differential equations systems using blitz++ for array and tensor manipulations and MPI for distributed parallelism.

Getting Started

Build and development support has broadened from linux only to Mac OSX and Windows systems. Tested with GNU make (written to be cross-platform) and g++ on linux/MinGW64, c++ on Mac OSX Sierra. Our build system depends on the cross-platform cmake tooling for Makefile generation.

  1. git clone https://github.com/dsteinmo/blitzdg.git
  2. cd blitzdg && ./pull-deps.sh
  3. cmake . && make && ./bin/advec1d (This binary is a 1D advection equation solver.).
  4. Run unit tests with make test.

Running with Docker

You can also run the build and tests inside a docker (linux) container. The container is based on an ubuntu 18.04 image.

  1. git clone https://github.com/dsteinmo/blitzdg.git && cd blitzdg
  2. docker build -t blitzdg .
  3. docker run -t blitzdg

Dependencies

So far:

  • cmake
  • blitz++
  • SuiteSparse (umfpack, cxsparse)
  • LAPACK
  • metis
  • boost
  • igloo for BDD-style testing.
  • vtk for visualization in Paraview.
  • boost-python for experimental python bindings.

Dependency installation is outlined in pull-deps.sh (tested on Ubuntu and Mac OSX).

Windows

The Windows build is currently deprecated due to lack of MinGW support of libvtk.

Contributing

We accept pull requests from public forks, and we use pull requests as the primary delivery mechanism of any new code within the base repository.

If you add code, please write tests using the igloo testing framework that is included as a project dependency. Your code additions will be subject to peer review and will be run through our Travis-CI continuous integration process.

Interested developers should consult the Guidelines for Contributing before getting started.
