Parameters below are shown in the format:   Name   (Valid Values)   [Default Value]

• GRACKLE_ACTIVATE   (0=off, 1=on)   [1]

  • Description: Enable the GRACKLE chemistry and cooling library.
  • Restriction: Only applicable when enabling the compilation option --grackle.

• GRACKLE_VERBOSE   (0=off, 1=on)   [1]

  • Description: Map to the "grackle_verbose" option in GRACKLE.
  • Restriction:

• GRACKLE_COOLING   (0=off, 1=on)   [1]

  • Description: Map to the "with_radiative_cooling" runtime parameter in GRACKLE.
  • Restriction:

• GRACKLE_PRIMORDIAL   (0=Cloudy, 1=6-species, 2=9-species, 3=12-species)   [0]

  • Description: Map to the "primordial_chemistry" runtime parameter in GRACKLE. One must increase --passive by 3, 6, or 9 for GRACKLE_PRIMORDIAL=1, 2, or 3, respectively.
  • Restriction:

• GRACKLE_METAL   (0=off, 1=on)   [0]

  • Description: Map to the "metal_cooling" runtime parameter in GRACKLE. One must increase --passive by 1 and initialize the field Metal using the field index Idx_Metal properly.
  • Restriction:

• GRACKLE_UV   (0=off, 1=on)   [0]

  • Description: Map to the "UVbackground" runtime parameter in GRACKLE.
  • Restriction:

• GRACKLE_CMB_FLOOR   (0=off, 1=on)   [1]

  • Description: Map to the "cmb_temperature_floor" runtime parameter in GRACKLE.
  • Restriction:

• GRACKLE_PE_HEATING   (0=off, 1=on)   [0]

  • Description: Map to the "photoelectric_heating" runtime parameter in GRACKLE.
  • Restriction:

• GRACKLE_PE_HEATING_RATE   (≥0.0)   [8.5e-26]

  • Description: Map to the "photoelectric_heating_rate" runtime parameter in GRACKLE. Note that the input value should always be in units of erg cm^-3 s^-1.
  • Restriction:

• GRACKLE_CLOUDY_TABLE   (string)   [none]

  • Description: Map to the "grackle_data_file" runtime parameter in GRACKLE.
  • Restriction:

• GRACKLE_THREE_BODY_RATE   (0=Abel+02, 1=Palla+83, 2=Cohen+83, 3=Flower+07, 4=Glover+08, 5=Forrey+13)   [0]

  • Description: Map to the "three_body_rate" runtime parameter in GRACKLE.
  • Restriction:

• GRACKLE_CIE_COOLING   (0=off, 1=on)   [0]

  • Description: Map to the "cie_cooling" runtime parameter in GRACKLE.
  • Restriction:

• GRACKLE_H2_OPA_APPROX   (0=off, 1=Ripomonti+04)   [0]

  • Description: Map to the "h2_optical_depth_approximation" runtime parameter in GRACKLE.
