blitzdg is an open-source library offering discontinuous Galerkin (dg) solvers for common partial differential equations systems using blitz++ for array and tensor manipulations in a C++ environment or NumPy as a Python 3 library.

Support blitzdg: 
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, clang++ on Mac OSX High Sierra, and MSVC on Windows. Our build system depends on the cross-platform cmake tooling for Makefile generation.

Dependency installation is outlined in pull-deps.sh (tested on Ubuntu and Mac OSX).
Our windows distribution was recently switched from MinGW to MSVC in order to achieve better support for graphics APIs, so support is lacking at the moment. Instructions will be made available here soon.
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.
We actively maintain an interactive set of docs using Doxygen for end-user consumption.
The documentation is available on github pages at https://wqcg.github.io/blitzdg and is kept synchronized with the master branch via automation.
