Run the Euler-Poisson case

The Euler-Poisson case lives in adc_cases, not in this repository: adc_cpp is the solver, adc_cases holds the named scenarios. This page shows how to run it.

Prerequisites

  • The pops Python module, built from adc_cpp. See Installation.

  • A local clone of adc_cases.

Run it

  1. Clone adc_cases and enter the case folder:

    git clone https://github.com/wolf75222/adc_cases.git
cd adc_cases/euler_poisson

  2. Run the case:

    python run.py

    The script advances the case and writes its figures to the case figures/ folder.

What it demonstrates

The case couples a compressible gas (the hyperbolic Euler part) to a self-gravitating potential (the elliptic Poisson part): the density sources the potential, and the potential gradient drives the gas. It exercises the conservative transport and the elliptic solve together.
