Runtime Parameters: General

Parameters described on this page: BOX_SIZE,   NX0_TOT_X,   NX0_TOT_Y,   NX0_TOT_Z,   END_T,   END_STEP,   TESTPROB_ID  

Other related parameters: none

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

• BOX_SIZE   (>0.0)   [none]

  • Description: Simulation box length along the longest dimension of (NX0_TOT_X, NX0_TOT_Y, NX0_TOT_Z). It must conform to the adopted unit system (see Unit Consistency).
  • Restriction:

• NX0_TOT_X   (≥16)   [none]

  • Description: Number of root-level cells along x.
  • Restriction: Must be a multiple of 16 (i.e., two patches).

• NX0_TOT_Y   (≥16)   [none]

  • Description: Number of root-level cells along y.
  • Restriction: Must be a multiple of 16 (i.e., two patches).

• NX0_TOT_Z   (≥16)   [none]

  • Description: Number of root-level cells along z.

  • Restriction: Must be a multiple of 16 (i.e., two patches).

• END_T   (≥0.0; <0.0 → set to default)   [depend]

  • Description: Simulation end time. END_T<0.0 is allowed only during restart (i.e., OPT__INIT=2, for which it will be reset to the value stored in the restart file) or if it will be reset by the adopted test problem. It must conform to the adopted unit system (see Unit Consistency).
  • Restriction:

• END_STEP   (≥0; <0 → set to default)   [depend]

  • Description: Simulation end root-level step. END_STEP<0 is allowed only during restart (i.e., OPT__INIT=2, for which it will be reset to the value stored in the restart file) or if it will be reset by the adopted test problem. For END_STEP=0, the program will still construct and output the initial condition before termination.
  • Restriction:

• TESTPROB_ID   (≥0)   [0]

  • Description: Test problem ID. See Test Problems for details. It currently supports

    • 1: blast wave [HYDRO]
    • 2: acoustic wave [HYDRO]
    • 4: cluster merger [HYDRO + GRAVITY + PARTICLE]
    • 5: AGORA isolated disk galaxy [HYDRO + GRAVITY + PARTICLE + SUPPORT_GRACKLE + STAR_FORMATION]
    • 6: caustic wave [HYDRO]
