1. Purpose

Provide storage for the hydro variables

2. Definitions

The HydroBase variables correspond to the Valencia formulation.

HydroBase uses the following conventions: M = M_sun c = G = 1

We also assume the following constants of nature: c = 299792458.0 m/s G = 6.67428e-11 m^3/kg/s^2 mu0 = 4 pi 1.0e-7 N/A^2 eps0 = 1 / (mu0 c^2) M_sun = 1.98892e+30 kg

This corresponds to the following units: [M] = M_sun [L] = [M] (G / c^2) [T] = [L] / c [B] = 1 / [L] / sqrt(eps0 G / c^2))
