Question
Got the following error while simulating the assignment problem with the parameter specified. 
<table><tbody><tr><td></td><td></td><td></td><td></td><td>Liquid Product: PR EOS: unable to find a root with provided parameters [T = 698.15 K, P = 20000000 Pa, MoleFracs={ NaN, NaN, NaN, }]

I am using DWSIM 6.0 Update 6 on Windows 10.

Used Nitrogen as BC with 20% Conversion.

And Isothermic Calculation mode in the Reactor.

Answers:

The simulation works fine for me for the following conditions:

Reaction Phase: Vapor/Mixture
Reactor Mode: Isothermal

Make sure that you are entering the feed composition correctly. If you still continue to face errors, please send your simulation files at contact-dwsim@fossee.in
