IsActivityModelType This should be set to True if the property package
can be considered an activity model property
package. A number of flash algorithms in HYSYS
optimize their algorithms based on the value of
this data member.
CanExchangeComponents This member should be set to True if the property
package can handle changes to the location of
components in the component slate.
CanCalculateFugacity This should be set to True if the property package
has implemented the ComputePhaseFugacities
method. If it is set to False, this method is never
called.
CanCalculateLLE This should be set to True if the property package
can calculate liquid-liquid equilibrium calculations
using the inside-out algorithm. If this is set to
True, the property package must implement the
ComputeHInnerParamsLL and ComputeKFactorsLL
methods.
CanHandleOilHypos If the property package can handle Oil
hypotheticals, this should be set to True. If it is set
to False, the user is not allowed in to the Oil
Environment.
UseGFlashInDynamics This flag is used to optimize thermodynamic
calculations in dynamics. If is recommended that
this be set to True unless the property package is
an equation of state.
CanHandleInsideOutPHFlash This flag disables the inside-out enthalpy flash if it
is set to False. It is recommended that this flag be
set to True unless the property package operates
on a narrow temperature range.
