TQSETR

Fortran

TQSETR (INDEXC, INDEXP, TEMP, PRES, IWSG, IWSE)
C-interface

tq_setr(TC_INT indexc,TC_INT indexp,TC_FLOAT temp,TC_FLOAT press,TC_INT* iwsg, TC_INT* iwse);

Full name:

Set Reference State.

Purpose:

Reset the reference state of a system component.

Comments:

By default the reference state for a component is determined by the thermodynamic data file. With this subroutine an application may select a different reference state if the one in the data file does not suit a calculation purpose. If the current temperature or pressure should be used for the calculation, the value given should not be larger than zero.

Note the following conventions to distinguish between the programming languages.

  • Routines starting with TQXXX, for example, TQGDAT, are in the Fortran interface
  • Routines starting with tq_xxxx, for example tq_gdat, are in the C-interface.
  • In Fortran, all routines are subroutines and do not return any values except where explicitly declared as functions.
  • All the C procedures are declared as void and do not return any values except where explicitly otherwise declared.
