                                     TASverter
              Thermal Analysis for Space software model converter
                              version r2013-06-30

 The program must be started with:
 
     TASverter [options]

 in which [options] are defined as follows:

 The following options specify the name and the format of the input model file.
 One of these options has to be specified:
 --from_SYSBAS=SOURCE_FILE.SYSBAS
   Sets the Thermica V3.2 SYSBAS file SOURCE_FILE as source model file
 --from_VIF=SOURCE_FILE.VIF
   Sets the Thermica V3.2 VIF file SOURCE_FILE as source model file
 --from_erg=SOURCE_FILE.erg
   Sets the ESARAD 5.1 geometry file (.erg) SOURCE_FILE as source model file
 --from_BDF=SOURCE_FILE.BDF
   Sets the NASTRAN BDF file (.BDF) SOURCE_FILE as source model file
 --from_GFF=SOURCE_FILE.GFF
   Sets the ESATAN GFF file (.GFF) SOURCE_FILE as source results file
 --from_TRASYS=SOURCE_FILE.inp
   Sets the TRASYS INP file (.inp) SOURCE_FILE as source model file
 --from_TAS=SOURCE_FILE.stp
   Sets the STEP-TAS part 21 file SOURCE_FILE as source model file

 The following options specify the name and format of the output model file.
 One of these options has to be specified:
 --to_SYSBAS=DEST_FILE.SYSBAS
   Sets the Thermica V3.2 SYSBAS file DEST_FILE as destination model file
 --to_erg=DEST_FILE.erg
   Sets the ESARAD 5.1 geometry file (.erg) DEST_FILE as destination model file
 --to_PAT=DEST_FILE.ses
   Sets the PATRAN session file DEST_FILE as destination model file
 --to_TRASYS=DEST_FILE.inp
   Sets the TRASYS file DEST_FILE as destination model file
 --to_csv=DEST_FILE.csv
   Sets the comma separated value file DEST_FILE as destination model file
 --to_patran_nodal_results=DEST_FILE
   Creates results files and templates in the MSC Patran Nodal Results format.
   A Patran Session file is also produced that can be run to automatically
   load the results into a Patran Database
 --to_TAS=DEST_FILE.stp
   Sets the STEP-TAS part 21 file DEST_FILE as destination model file

 Additional options are:
 --renumber
   Activates the node renumbering feature. This option needs a file called
   "SOURCE_FILE.renumber".
   This option can be used as a work around in cases where the maximum thermal
   node number of the original model exceeds the maximum thermal node number
   supported by the code for the generated model.
   See also the description under the option --make_renumber_template

 --make_renumber_template
   Forces the generation of a template for the renumbering input file. It will
   also generate a sorted list with thermal node numbers from which the free
   node number ranges can be derived. This option is activated as soon as the
   maximum node number in the original model exceeds the maximum supported node
   number of the code to be used for the generated model.

   To apply the desired renumbering scheme:

   - Rename the file SOURCE_FILE.renumber.template" to SOURCE_FILE.renumber
   - Edit the file SOURCE_FILE.renumber to apply the desired renumbering.
     The format of the file is explained in the comments in the generated 
     template file.
   - Re-run TASverter, this time with the option "--renumber":

   TASverter --renumber --from_xxx=SOURCE_FILE.XXX --to_yyy=DEST_FILE.YYY

 --inactive_node=INACTIVE_NODE
   Assigns the specified node number to both sides of double side inactive
   faces, i.e. both sides of a surface are inactive (e.g. due to nrays=0 in
   THERMICA SYSBAS file). The thermo-optical properties solar absorptance
   (alpha) and infra-red emittance (epsilon) are always set to 1.0 for both 
   sides of double inactive faces.
   Default value: inactive_node=99998.

 --double_sided_gap=DOUBLE_SIDED_GAP
   In some codes (e.g. in THERMICA) it is not possible to have different
   thermal node numbers at the two sides of a surface. A work around solution
   for this limitatation is to generate for these codes two single side active
   surfaces separated by a gap of size DOUBLE_SIDED_GAP. The single side
   active surfaces are offset from the original position over a distance of
   + and - 0.5*DOUBLE_SIDED_GAP in the direction of the local normal. This
   gap helps to prevent numerical problems during the radiative analysis.
   Default value: double_sided_gap=0.001000

 --all_warnings
   All warning messages generated will be printed on the screen
   This option overrides the option max_warnings_number

 --max_warnings_number=MAX_WARNINGS_NUMBER
   Specifies the maximum number of warnings messages of the same category that
   will be printed on the screen.
   Independently of this option, all warnings are recorded in the log file.
   Default value: max_warnings_number=10

 --material_environment=MATERIAL_ENVIRONMENT
   Selects the preferred material environment in the case the source model
   contains more than one material environment and the format of the
   destination does not support multiple material environments.
   Default value: material_environment="" (empty string)
              This will cause the selection of the first material environment

 --source_length_unit=UNIT
   Specifies the length units used for the source model
   Valid length units are m (metre), cm (centimetre), mm (millimetre),
   in (inch) and ft (foot)
   Default value: m or the unit specified in the source model file.

 --destination_length_unit=UNIT
   Specifies the length units used for the destination model
   Valid length units are m (metre), cm (centimetre), mm (millimetre),
   in (inch) and ft (foot)
   Default value: m or the unit implicitly used by the destination model format

 --facet_angle=ANGLE
   Specifies the angle in degrees to be spanned by the conical facets used to
   approximate the TRASYS spheroid, ogive and toroid.
   Default value: facet_angle = 15.000000
