PYGMG -- HPGMG in Python

This is a simple python reference implementation of the HPGMG project

Quick Start

How to get things up and running from the command line. This assumes you have a working version python running and accessible from the shell and that you have installed pip and it works too. Given all that, from the shell:

git clone https://github.com/ucb-sejits/pygmg.git
cd pygmg
pip install -e .

You are now ready to run, first use the run script with --help to see the options. And then do a simple run to see what happens.

./run_finite_volume --help
./run_finite_volume 4 -d 2 -nv 20

Using iPython

Once you have it running as above, a good way to visualize what is happening is to us ipython. From the command line.

ipython notebook

This creates a local web service running on localhost:8888 (on a laptop or desktop this command will usually take you to the browser. Select the notebooks folder and then try the SimpleSolver-HeatMap-2D notebook. It is set up to show intermediate files to provide visual clues as to whether things are working properly.
