Nik posted a comment on discussion Python Scripting
Solved using "float" in the Set function: oms1.SetOverallCompoundMassFlow('Methane',float(outWFCH4))

Hi again, I have tried with creating a project from scratch without involving Cantera and the function i.e. oms1.SetOverallCompoundMassFlow('Methane',outCH4) works as expected. Is there a way to print outputs from a Python script for debugging? thanks a lot

Thanks, Daniel. I got another error saying "an integer is required". I can go around the issue by rounding the number but that would not be numerically correct. Something I should do to troubleshoot the code? Set the properties on the Outlet Material Stream connected to Port 1(oms1) oms1.Clear() Set operative conditions oms1.SetTemperature(T) oms1.SetPressure(P) oms1.SetMassFlow(WF) Read mass fractions from cantera mixture. See the original 'gri30.yaml' file to inspect compound indexes in the array...

Thanks, Daniel. I will correct the calculations above to make sure mass and molar balances are respected. About the compound index, I guess it is the one defined in DWSIM: how can I get to know compound indexes? is there any function I could call? Anyhow, the note on the function says "String". see attached screenshot Thanks a lot

Thanks, Daniel. I have corrected the typo "mass" with "molar" above for reference for future readers.

Hi everyone, I am new to DWSIM and I am trying to set a model based on Cantera Interop. I am using python 3.9 (portable version as suggested by Daniel) and have checked already that Cantera is installed and functioning. All good till here. The issue I have is similar to what Pietro reported here above a couple of years back: when running: "oms1.Phases[0].Compounds['Methane'].MoleFraction = System.NullableSystem.Double" I get an error message saying: "Error in 'Python.Runtime': module 'System' has...
