Isothermal disc hydrodynamics with a Roe solver
Project description
Pyrodeo
Pyrodeo is a Python implementation of the isothermal hydrodynamic solver RODEO (ROe solver for Disc-Embedded Objects). Its main purpose is to perform numerical simulations of astrophysical (gas) discs.
Features
- Two- and three-dimensional inviscid isothermal hydrodynamics using a Riemann solver.
- Second order in space and time in regions of smooth flow.
- Different geometries: Cartesian, Shearing Sheet, cylindrical coordinates and spherical coordinates.
- HDF5 output
Quick start
Pyrodeo can be installed from the command line simply by entering:
pip install pyrodeo
A simple simulation can be created and run by entering:
import pyrodeo sim = pyrodeo.Simulation.from_geom('cart') sim.evolve([0.25])
Since the standard initial conditions consist of constant density and pressure and zero velocity, no visible evolution takes place. For more interesting examples, see the documentation.
