Detailed Description

Constant solution to M1 equations in Minkowski spacetime.

An analytic solution to the 3-D M1 system. The user specifies the mean flow velocity of the fluid and the radiation energy density in the fluid frame J. The radiation is taken to be in equilibrium with the fluid (i.e. comoving, with an isotropic pressure P=J/3)
