void | InitDomain (Data *d, Grid *grid) |
Set the initial condition for the 2D or 3D shock-cloud problem. The shock propagates in the x-direction and it is initially located at x=0.6
with post- and -pre shock value equal to
while the remaining vector components are 0. The cloud has radius centered at
and larger density
.
The interaction may be divided into two phases: 1) the collapse stage where the front of the cloud is strongly compressed and two fast shocks are generated and 2) the reexpansion phase which begins when the transmitted fast shock overtake the back of the cloud.
The runtime parameters that are read from pluto.ini
are
g_inputParam[B_POST]
: sets the post-shock magnetic field;g_inputParam[B_PRE]
: sets the pre-shock magnetic field;g_inputParam[RADIUS]
: sets the radius of the cloud;A list of the available configurations is given in the following table:
