Relativistic Blast Wave with Newtonian Gravity. More...
Set the initial condition for a blast wave problem in RHD in the presence of a Newtonian gravitational field. Ambient density and pressure are constant everywhere and equal to rho0
and p0
. While rho0
is an input parameter, p0=1.e-5
. A large amount of energy is deposited in a small spherical volume, with radius R=0.5
. The TAUB equation of state is applied, with initial polytropic index gamma=4
./3. . The Newtonian gravitational field is introduced by enabling the BODY_FORCE flag in definitions.h and setting it to VECTOR. The field is assumed to be isotropic and generated by a point mass located at the origin. The value of the point mass MASS
(in unit of solar masses) is an input parameter.
The input parameters read from pluto.ini are labeled as:
g_inputParam[ENRG0]
: initial energy of the blast wave (not energy density);g_inputParam[DNST0]
: initial constant density;g_inputParam[MASS]
: central point mass.The available configurations refer to:
