This option specifies that liquid and vapor Viscosities, liquid and vapor Thermal Conductivities and liquid Surface Tensions will be calculated by a User-added subroutine (UAS). Up to five different transport property subroutines (with reserved names UTRAN1 - UTRAN5) may be linked into PRO/II.
For details on how to link User-added subroutines into PRO/II, consult the UAS/PDTS Installation Guide, available from SimSci. For details on how to construct User-added subroutines, consult the PRO/II User-added Subroutines User's Manual, also available from SimSci.
