Rotation Parameters

The &rot namelist group defines rotational parameters; the input file can contain one or more, but only the last (matching) one is used. Allowable parameters are:

coriolis_method (default 'NULL')

Method used to treat the Coriolis force; one of:

  • 'NULL' : Neglect the Coriolis force
  • 'TAR' : Use the traditional approximation of rotation
Omega_rot_source (default 'MODEL')

Sourcce for rotational angular velocity; one of:

  • 'MODEL' : Use data from the stellar model
  • 'UNIFORM' : Uniform rotation, with angular velocity set by Omega_rot parameter
Omega_rot (default 0)
Rotation angular frequency (when Omega_rot_source is 'UNIFORM')
Omega_rot_units (default 'NULL')

Units of Omega_rot (when Omega_rot_source is 'UNIFORM'); one of:

  • 'NONE' : Dimensionless angular frequency
  • 'HZ' : Linear frequency in Hz [1]
  • 'UHZ' : Linear frequency in μHz [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]
complex_lambda (default .FALSE.)
Flag to use complex arithmetic when evaluating the TAR angular eigenvalue \(\lambda\)
tag_list (default '', which matches all)
Comma-separated list of &mode tags to match
