7.1.17 Radiation-transport control (MSrad only)

7.1.17.1 integer n_radtheta

Using the MSrad module the ray directions have to specified in a different way: The number of ray sets in theta direction can be chosen with e.g.

integer n_radtheta f=I4 b=4 &
    n='NTHETA: Number of ray sets in theta direction' c0=2
2

7.1.17.2 integer n_radphi

Using the MSrad module the number of ray sets in phi direction can be set e.g. with

integer n_radphi f=I4 b=4 &
    n='NPHI: Number of ray sets in phi direction' c0=2
2

7.1.17.3 integer n_radsubray

Using the MSrad module the number of rays per cell (with the same direction) can be specified e.g. with

integer n_radsubray f=I4 b=4 n='KPHI: Number of rays per cell' c0=2
2

7.1.17.4 integer n_radthickpoint

With the MSrad module the lower part of the model can be computed in diffusion approximation. The number of points in diffusion approximation can be set with e.g.

integer n_radthickpoint f=I4 b=4 &
  n='Number of grid points with optically thick (diff.) approximation' &
  c0='0: no diffusion approximation'
0

The value should be choosen so that for all points in that region $\Delta\tau > 1$ is valid. Setting this value to 0 means that the diffusion approximation is not used in any part of the model.

7.1.17.5 integer n_radtaurefine

With the LHDrad and the MSrad module, the number of points on the rays can be finer than the number of points in the basic numerical grid. The refinement can be set e.g. with

integer n_radtaurefine f=I4 b=4 &
  n='Refinement factor'
0

7.1.17.6 integer n_radrsyslevel

This parameter specifies the "zero" point of the ray system, default: 0 (MSrad only). The parameter is specified with e.g.

integer n_radrsyslevel f=I4 b=4 n='Zero index of ray system' &
  c0='0: (default)' &
0

7.1.17.7 integer n_radoutput

This parameter controls additional output into the file 'rhd.qrad', default: 0 (MSrad only). The parameter is specified with e.g.

integer n_radoutput f=I4 b=4 n='Output level of MSrad' &
  c0='0: (default)' &
1

7.1.17.8 real c_radtcool

Parameter for surface cooling option (N_radband$\le$0) of MSrad. It can be activated with the parameter

real c_radtcool f=E15.8 b=4 &
  n='Surface cooling'            u=1 &
  c0='0.0: default'
0.0

7.1.17.9 real c_raddcool

Parameter for surface cooling option (N_radband$\le$0) of MSrad. It can be activated with the parameter

real c_raddcool f=E15.8 b=4 &
  n='Surface cooling'            u=1 &
  c0='0.0: default'
0.0

7.1.17.10 real c_radscool

Parameter for surface cooling option (N_radband$\le$0) of MSrad. It can be activated with the parameter

real c_radscool f=E15.8 b=4 &
  n='Surface cooling'            u=1 &
  c0='0.0: default'
0.0

7.1.17.11 real c_radtinci

Temperature of black body that emits incident radiation, default: 0.0, (MSrad only). It can be used e.g. with

real c_radtinci f=E15.8 b=4 &
  n='Temperature of black body that sends incident radiation' u=K &
  c0='0.0: default'
0.0

7.1.17.12 real c_raddinci

Dilution factor $(R_{*}/d)^2$ of black body that emits incident radiation, default: 0.0, (MSrad only). It can be used e.g. with

real c_raddinci f=E15.8 b=4 &
  n='Dilution factor of black body that sends incident radiation' u=1 &
  c0='0.0: default'
0.0
