Orbit Namelist Group

The &orbit namelist group defines orbital parameters. The input file can contain one or more, but only the last (tag-matching) one is used. The following options are available:

Omega_orb (type: real, default: 1)

Orbital angular frequency

Omega_orb_units (type: string, default: 'NONE')

Units of Omega_orb; one of

  • 'NONE' : Dimensionless angular frequency

  • 'HZ' : Linear frequency in Hz[1]

  • 'UHZ' : Linear frequency in \(\mu\)Hz[1]

  • 'RAD_PER_SEC' : Angular frequency in radians per second[1]

  • 'CYC_PER_DAY' : Linear frequency in cycles per day[1]

  • 'CRITICAL' : Fraction of the Roche critical rate[1]

q (type: real, default: 1)

Ratio of secondary mass to primary mass

e (type: real, default: 0)

Orbital eccentricity

tag_list (type: string, default: '')

Comma-separated list of tag values to match; matches all if left blank
