Application

The USERF routine must interpret the values of ITAB and CHARA to determine which particular relationship is requesting a value for and then use IDEP to determine which element or conductance is currently being processed. Once this data has been processed the code can implement the appropriate calculations and return a value in the variable VDEP. This value will be applied to whatever variable is defined as the independent variable in the Card 9 - TABTYPE Table Variable Type Definition Card - Optional. For more information, see the Thermal Solver Reference Manual PDF.

All the techniques recommended for USER1 subroutines can also be used in USERF as can all of the thermal solver functions. USERF subroutines can be created and managed in the same way as the user written subroutine USER1.
