Set the initial condition for the relativistic magnetized blast wave problem in 2D or 3D. It consists of a highly pressurized region inside a circle (in 2D) or a sphere (in 3D) embeddd in a static uniform medium with lower pressure. The magnetic field is constant and threads the whole computational domain.
In 3D, a linear smoothing is applied in the region . The input parameters used in this problem are:
g_inputParam[PRS_IN]
: pressure inside the initial circular (2D) or spherical (3D) region.g_inputParam[PRS_OUT]
: ambient pressureg_inputParam[RHO_OUT]
: ambient densityg_inputParam[BMAG]
: magnetic field intensityg_inputParam[THETA]
: angle between mag. field and z-axis (Cartesian only )g_inputParam[PHI]
: angle between mag. field and xy-plane (Cartesian only)g_inputParam[RADIUS]
: radius of the initial over-pressurized region.Note that a given choice of parameters can be re-scaled by an arbitrary factor by letting
.
The different configurations are:
Strongly magnetized configurations can pass this test only by taking some precautions (e.g. correcting total energy with staggered magnetic field).
