Detailed Description

Analytic initial data for a slab jet.

This test problem is described in [121], Section 7.4 and Fig. 13. It involves a high Lorentz factor jet injected into an ambient fluid with an initially uniform magnetic field.

The parameters used in [121] are:

AdiabaticIndex: 4. / 3.
AmbientDensity: 10.
AmbientPressure: 0.01
JetDensity: 0.1
JetPressure: 0.01
# u^i = [20, 0, 0] or W = sqrt(401)
JetVelocity: [0.9987523388778445, 0., 0.]
InletRadius: 1.
MagneticField: [1., 0., 0.]

In [121] an artificial dissipation of \(\eta_u=0.2\) and \(\eta_b=0.15\) is used, which we don't use here (yet).

Note: The inlet is currently modeled as the region of the domain where \(x <= 0\) and \(|y| <= \mathrm{inlet_radius}\). Since this class only sets the initial data, no fluid will flow into the domain during the evolution. This has to be modeled as a boundary condition and is not implemented yet.
