7.3 IDL Data Structure

The data structure FUL contains the following variables and substructures. Use help,/str,ful, to get this information. See also the short description of the contents of a model file in Sect. 5.1 and particularly the man-page of the script uiolook in Sect. 4.6.1 which gives you even more detailed information directly from the file:

<> ** Structure <8287a0c>, 9 tags, length=78404128, refs=1:
   TYPE               STRING    'uio'
   HEAD               STRUCT    -> <Anonymous> Array[1]
   DATASET_ID         STRING    'single_box'
   MODELTIME          FLOAT           10050.1
   MODELITIME         LONG            64088
   DTIME              FLOAT               0.176381
   TIME_OUT_FULL_LAST FLOAT           10050.1
   TIME_OUT_MEAN_LAST FLOAT           10040.0
   Z                  STRUCT    -> <Anonymous> Array[1]

If the command in Sect.7.2.5 has been performed, the following substructures are present:

<>    EOS                STRUCT    -> <Anonymous> Array[1]
   OPA                STRUCT    -> <Anonymous> Array[1]

The substructure FUL.Z contains the original data arrays from the model file like the spatial axes, density rho, internal energy ei, and the three spatial components of the velocity (v1, v2, v3):

<> ** Structure <8274184>, 16 tags, length=78403900, refs=2:
   TYPE               STRING    'uio'
   BOX_ID             STRING    'z'
   DIMENSION          LONG      Array[2, 3]
   TIME               FLOAT           10050.1
   ITIME              LONG            64088
   XC1                FLOAT     Array[140, 1  , 1  ]
   XC2                FLOAT     Array[1  , 140, 1  ]
   XC3                FLOAT     Array[1  , 1  , 200]
   XB1                FLOAT     Array[141, 1  , 1  ]
   XB2                FLOAT     Array[1  , 141, 1  ]
   XB3                FLOAT     Array[1  , 1  , 201]
   RHO                FLOAT     Array[140, 140, 200]
   EI                 FLOAT     Array[140, 140, 200]
   V1                 FLOAT     Array[140, 140, 200]
   V2                 FLOAT     Array[140, 140, 200]
   V3                 FLOAT     Array[140, 140, 200]

Spatial axes: XC1, XC2, XC3, XB1, XB2, XB3:

The indices stand for 1:x, 2:y, 3:z. C for the grid cell centre, B for the boundaries. Most of the quantities are defined for the cell centres. In case of doubt, this can be found out by checking the array dimensions.

The substructure FUL.EOS contains important quantities like the temperature T, gas pressure P, entropy S:

<> ** Structure <826a03c>, 6 tags, length=109760000, refs=2:
   P                  FLOAT     Array[140, 140, 200]
   DPDRHO             FLOAT     Array[140, 140, 200]
   DPDEI              FLOAT     Array[140, 140, 200]
   T                  FLOAT     Array[140, 140, 200]
   DTDEI              FLOAT     Array[140, 140, 200]
   S                  FLOAT     Array[140, 140, 200]

The substructure FUL.OPA only contains the opacity KAPPA:

<> ** Structure <826a5b4>, 1 tags, length=15680000, refs=2:
   KAPPA              FLOAT     Array[140, 140, 200]
