Card 0 - Equilibrium calculation switches

• IRST1 - (obsolete).

• IRST2 - (obsolete).
• NDOUB - Number of times number of grid zones is doubled = NDOUB

• IPSI - Radial coordinate switch.

  0.0 Radial coordinate is .

  1.0 Radial coordinate is .

• IFUNC2 - Profile form switch for parallel current, p, n, and T. IFUNC2 is a 3 digit number of the form i₃i₂i₁. Note:

  Profile functional form switch:

  i₃ = 0 Profile .

  Profile information is taken from cards 2, 3, 9, and 10.

  i₃ = 1 Profile 3 region cubic spline representation.

  Profile information is taken from cards 16, 17, 18, and 19.

  Pressure profile switch:

  i₂ = 0 Central density determined by P0 and TZER0.

  n profile determined from p and T profiles.

  i₂ = 1 Central density determined by P0 and TZER0.

  p profile determined from n and T profiles.

  i₂ = 2 Central pressure determined by DZERO and TZER0.

  p profile determined from n and T profiles.

  Parallel current profile switch:

  i₁ = 1 User-specified parallel current function.

  i₁ = 2 High bootstrap-fraction model.

  i₁ = 3 Self-consistent ohmic model.

  i₁ = 4 Read in profiles from TSC. Requires NetCDF eqdska input file.

  If i₁=4 and IFUNC2 is negative, only read in plasma shape.

  i₁ = 5 Self-consistent ohmic-bootstrap model.

  If i₁ = 3 or 5, i₂ is set to 2 internally.

• IFILE - Number of records skipped in file EQDSKA when IFUNC2 = 4.

• NUMIT - Maximum number of metric outer interations before quitting.
