    Is there any code to extract the density and viscosity of the compound using the command rho1=Flowsheet.SelectedCompounds['hydrogen'].density

    It was showing the error as it is not attributed to constant property

    Vapor phase density is not available for single compounds. DWSIM calculates the density for the entire vapor phase mixture.

    To get the density of the whole vapor phase, use

    vapdens = stream.PropertyPackage.AUX_VAPDENS(T_in_K, P_in_Pa) # density in kg/m3

    Sir, can you please share some source code regarding extracting and viscosity for the overall compound

    Overall compound or overall phase?

    visc = stream.GetPhase("Vapor").Properties.viscosity # Pa.s
dens = stream.GetPhase("Vapor").Properties.density # kg/m3
