Relativistic Reactive Riemann problem solver for Deflagrations and Detonations

Relativistic Reactive Riemann problem solver for Deflagrations and Detonations

This extends standard solutions of the relativistic Riemann Problem to include a reaction term.

Installation

A standard:

python setup.py install

or:

pip install r3d2

should work.

Usage

Import the equations of state, State class, and Riemann Problem class:

>>> from r3d2 import eos_defns, State, RiemannProblem

Set up an equation of state:

>>> eos = eos_defn.eos_gamma_law(5.0/3.0)

Set up the left and right states:

>>> U_L = State(rho=1.0, v=0.0, vt=0.0, eps=1.5, eos=eos)
>>> U_R = State(rho=0.125, v=0.0, vt=0.0, eps=1.2, eos=eos)

Solve the Riemann Problem:

>>> rp = RiemannProblem(U_L, U_R)

The output can be examined for details of the solution and its wave structure. However, the classes are optimized for display in a Jupyter notebook. See the documentation for more detail.
