Detailed Description

Periodic GrMhd solution in Minkowski spacetime.

An analytic solution to the 3-D GrMhd system. The user specifies the mean flow velocity of the fluid, the wavevector of the density profile, and the amplitude $A$ of the density profile. The magnetic field is taken to be zero everywhere. In Cartesian coordinates $(x,y,z)$, and using dimensionless units, the primitive quantities at a given time $t$ are then

$$\begin{array}{rl}\rho (\overrightarrow{x},t)& =1+A\sin (\overrightarrow{k}\cdot (\overrightarrow{x}-\overrightarrow{v}t))\\ \overrightarrow{v}(\overrightarrow{x},t)& =[v_x,v_y,v_z{]}^T,\\ P(\overrightarrow{x},t)& =P,\\ ϵ(\overrightarrow{x},t)& =\frac{P}{(\gamma -1)\rho }\\ \overrightarrow{B}(\overrightarrow{x},t)& =[0,0,0{]}^T\end{array}$$
