Bachelor Thesis Structure preserving Lax-Wendroff schemes for low Mach number flows from Jonas Bachmann.
Simply execute pip install -e . to set up the project.
For storing trajectories instead of keeping them in memory, FFmpeg is required.
Example usage of evolving the Euler equations in 2D with the linearized solutions from 1D (Euler.waves).
