TQSCOM(NCOM, NAMES, STOI, IWSG, IWSE)
C-interface

tq_scom(TC_INT num,tc_components_strings* components,TC_FLOAT* stoi,TC_INT* iwsg,TC_INT* iwse);

Full name:

Set System Component.

Purpose:

A new set of system components can be defined. The new number of components must be the same as previously. The number of system components can be changed by suspending a component by TQCSSC.

Comments:
  • The set of components must be linearly independent.
  • The names of the new system components are given in NAMES.
  • STOI is a matrix with dimension STOI (1:NCOM,1:NCOM) which gives the stoichiometry of the new components expressed in the old ones.
  • The default set for components is taken from in the input thermodynamic data file.
  • Legal values for the array elements in NAMES are constituent names.
  • The components are numbered as 1 NCOM in the order they are supplied in this call. The conversion from component name to index is also done by TQGSCI.

For example, to transform from the components A, B, C to A2B, B4CC2 use the following values of STOI:

A2B2.0 1.0 0.0

B4C 0.0 4.0 1.0

C2 0.0 0.0 2.0

Arguments

NAMES

Character*24 array

Stoichiometry matrix in old components.

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.
