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{align*} \rho(\vec{x},t) &= 1 + A \sin(\vec{k}\cdot(\vec{x} - \vec{v}t)) \\ \vec{v}(\vec{x},t) &= [v_x, v_y, v_z]^{T},\\ P(\vec{x},t) &= P, \\ \epsilon(\vec{x}, t) &= \frac{P}{(\gamma - 1)\rho}\\ \vec{B}(\vec{x},t) &= [0, 0, 0]^{T} \end{align*}
