TEMPT

Bulk Data Entry Defines parameters for mapping the grid temperature field from either an external file or an internal heat transfer subcase to Nonlinear Static Analysis. The mapping is over time-domain only.

Definitions

Field Contents SI Unit Example
ID Unique identification number. 2

No default (Integer > 0)

 
HST Heat source type.
HFILE
Thermal load is read from an external file.
HSUB
Thermal load is read from an internal transient heat transfer subcase.

No default

 
HSI Heat source identification number.

For HFILE, this field provides the identification number of the external file (ID defined on ASSIGN,HFILE).

For HSUB, this field provides the identification number of the internal transient heat transfer subcase.

No default (Integer > 0)

 
The various PARAMi definitions are listed below, along with their corresponding allowed VALUEi ranges and default values.
HTINI The initial time in HFILE/HSUB, at which the grid temperature field is used for nonlinear static analysis at subcase time = 0.0. If HTINI is not defined, the earliest time defined in the referenced HFILE/HSUB will be used. The time defined in HFILE/HSUB is global time.

Default = blank (Real)

 
HTFIN The final time in HFILE/HSUB, at which the grid temperature field is used for nonlinear static analysis at subcase time = TTERM (defined in NLPARM card). If HTFIN is not defined, the last time defined in the referenced HFILE/HSUB will be used. The time defined in HFILE/HSUB is global time.

Default = blank (Real)

 

Comments

  1. The TEMPT Bulk Data Entry is selected by the Subcase Information Entry TEMP(LOAD,TEMPT)=ID.
  2. TEMPT entry identification number should be unique with respect to the TEMP entry.
  3. The temperature field defined in HFILE/HSUB is a mapping from the time domain in between HTINI and HTFIN to nonlinear static analysis time domain linearly.

  4. In case that TEMP(INIT) is not defined in the deck file, the temperature field corresponding to HTINI is used as initial temperature field.
