Planck and Rosseland Means¶
doMean option in the
param.dat file, the Plank and Rosseland means,
\(\kappa_P\) and \(\kappa_R\) respectively:
can be calculated, where the infinity integral is truncated to the specified wavenumber limits, and \(d\nu\) is
dnu set in the
Note that the denominators in \(\kappa_P\) and \(\kappa_R\) can be computed analytically as
Therefor, it is usefull to compare those analytic results to the numerical integration
The results of the Planck and Resseland means are stored in the file
Out<name>_mean.dat, together with
the analytic and numerical expressions (10) to (13). If the numerical expressions deviate strongly
from the analytical expression, then it is a hint that the wavenumber resolution is not set fine enough.
An example of the Planck and Rosseland means is shown in Fig. 11.
