Thermal solver files

File name	Description
esatan.dat	Contains the ESATAN output format file created if Card 9 PARAM ESATAN is specified.
ExpandedElements.bun	Contains original elements and expanded elements. The expanded elements are created by rotating the original elements, used for axisymmetric and thermal rotational periodicity modeling, around the specified axis of rotation. It helps you verify whether you set up your model correctly, particularly when the software computes view factors where there are collisions between original and expanded elements. You can import this BUN file into a post-processing tool to visualize the original and duplicate elements in 3D.
FMODLF	Contains a thermal model in TRASYS, or SINDA formats, or element or node temperatures in the Nastran format. FMODLF is created if a Card 9 PARAM SINDA or PRAM TRASYS is present. The REFORM module writes in the FMODLF file. Content is always appended to FMODLF.
GTEMPF	The output file that contains node temperatures. Its format is identical to that of the TEMPF file, except that the temperatures are node temperatures. GTEMPF is created from the TEMPF file and the model geometry by the TMGINT module.
INPF	The primary input file used by the DATACH module. No input line may exceed 90 columns. All data in INPF is in free format, except for the optional Nastran format section in Card 4.

MODLF	Contains all the thermal couplings, radiative, conductive, hydraulic, and convective conductances, element capacitances, and heat loads calculated from elemental geometry and material and physical properties by the COND, GRAYB, VUFAC, and POWER modules. For more information, see MODLF.

Data is written in format: `(I7,2E15.7)` The data fields contain element number `I`, total pressure `PT(I)`, mass flow `MASSFL(I)`. If `I = -99999`, then the `PT(I)` value represents the printout time. If a Card 9 PSINK FPRESSF is present, all the hydraulic elements are defined as PSINK elements, with the constant pressures and constant mass flows read from the PRESSF file.

sinda85.dat	Contains a SINDA85 format output file created if Card 9 PARAM SINDA85 is specified.
TEMPF	Contains the calculated temperatures at the end of a run. The Analyzer module writes data on TEMPF at the printout intervals defined by the Card 2b DTP parameter. Alternatively, other software may create TEMPF. such as SINDA, for post-processing by TMG. TEMPF is used for post-processing by the TMGINT, FRONT, and REFORM modules. Data is written in format: `(I10,1PE23.15)` If at the start of a run a TEMPF file is present, its data is used as the initial temperatures. If Card 9 TINIT are also present, the temperatures of the TINIT cards override those of TEMPF. If it is not present, or contains an incomplete set of data, the Analyzer module for the undefined elements assumes zero initial temperatures. `I,TEMP(I)` `I` is the element number. `TEMP(I)` is the temperature of element `I`. If `I = -99999`, then `TEMP(I)` is the printout time value for subsequent temperatures.
