Most temperature derivatives and all pressure- and composition derivatives are done by perturbation as they are not supplied by refprop.dll. Composition derivatives for two-phase properties are not available in CAPE-OPEN version 1.0.

The following flash calculations are supported: temperature-pressure, volume-enthalpy(1.1), volume-entropy(1.1), volume-internal energy(1.1), temperature-enthalpy, temperature-entropy, pressure-volume(1.1), temperature-volume(1.1), pressure-enthalpy, pressure-entropy, entropy-enthalpy, pressure-internal(1.1) energy, temperature-vapor fraction and pressure-vapor fraction.

The flash calculations marked with (1.1) are only available when using the CAPE-OPEN version 1.1 standard.

Calculations are only supported within the range of validity defined by REFPROP.
