ConstantsΒΆ

The &constants namelist group defines various physical constants; the input file should contain exactly one. Allowable parameters are:

G_GRAVITY
Gravitational constant \(G\)
C_LIGHT
Speed of light in vacuo \(c\)
A_RADIATION
Radiation constant \(a\)
M_SUN
Solar mass \(M_{\odot}\)
R_SUN
Solar radius \(R_{\odot}\)
L_SUN
Solar luminosity \(L_{\odot}\)
GYRE_DIR
Top-level GYRE directory; overrides the GYRE_DIR environment variable

All of these constants are in cgs units (where applicable), and the default values are defined in src/common/gyre_constants.fpp.
