This Python 2.7 script uses the numerical method-of-lines to model gas injection into a one-dimensional system of variable geometry with a mobile, albeit unsaturated, water phase.
The script requires numpy, scipy, and matplotlib libraries.
The following tab-delimited input files are required:
- ICs.txt - initial conditions
- grid.txt - spatial discretization
- mat_list.txt - material distribution within column
- materials.txt - physical properties of porous media
- sources.txt - source/sink terms
- times.txt - output times
More background information can be found here: https://numericalenvironmental.wordpress.com/2016/07/11/multiphase-flow/
I'd appreciate hearing back from you if you find the script useful. Questions or comments are welcome at walt.mcnab@gmail.com.
