Numerical resolution of Euler's equations for incompressible fluids using semi-discrete optimal transport. This code goes with the article "A Lagrangian scheme for the incompressible Euler equations using optimal transport", by Thomas O. Gallouet and Quentin Mérigot.
This code requires MongeAmpere and PyMongeAmpere, available here:
https://github.com/mrgt/MongeAmpere
https://github.com/mrgt/PyMongeAmpere
Before running any of the programs, you need to set PYTHONPATH to the right location:
export PYTHONPATH=$PYTHONPATH:/path/to/PyMongeAmpere-buildOn a simple example:
mkdir results
python beltrami_square.py
