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.
