doublereal enthalpy_mole ( ) const

virtual

Note they have the same units, as their ratio is defined to be equal to the activity of the kth species in the solution, which is unitless.

This routine is used in print out applications where the units are needed. Usually, MKS units are assumed throughout the program and in the XML input files.

void initThermo ( )

virtual

Initialize the ThermoPhase object after all species have been set up.

Initialize.

This method is provided to allow subclasses to perform any initialization required after all species have been added. For example, it might be used to resize internal work arrays that must have an entry for each species. The base class implementation does nothing, and subclasses that do not require initialization do not need to overload this method. When importing a CTML phase description, this method is called from ThermoPhase::initThermoXML(), which is called from importPhase(), just prior to returning from function importPhase().
