The DWSIM inbuilt functions
Hello,where can I find all the DWSIM inbuilt functions? such as Getphase, Getprop, Setprop, WriteMessage and ...secondly, in DWSIM Flowsheet, I make stream called feed which is ims1. ims1 includes multiple components. I want to extract mole fraction of every component by Getprop function:ims1.GetProp('fraction', 'Overall', Ethylene, '', 'mole')ims1.GetProp('fraction', 'Overall', Oxygen, '', 'mole') . .but an Error occurs! 28/12/2021 5:24:59 PMErrorUO-01: KeyNotFoundException : The given key was not present in the dictionary. at System.ThrowHelper.ThrowKeyNotFoundException() at System.Collections.Generic.Dictionary`2.get_Item(TKey key) at DWSIM.Thermodynamics.Streams.MaterialStream.GetProp(String property, String phase, Object compIds, String calcType, String basis) in C:\Users\Daniel\source\repos\DanWBR\dwsim6\DWSIM.Thermodynamics\Material Stream\MaterialStream.vb:line 3255What should I do?Regards+ Info
