Rigourous Distillation column error with image file

Dear Sir/madam,

I am unable to simulate distillation column.

Error: Solver reached maximum iteration.

Tried with 2000 iterations, by changing property packages, by changing flash algorithms but same error remains.

Rigorous colum file is attached.

Please guide me.

Thanks and regards,

Varun Doshi

Did you try ChemSep column instead of rigorous column? Also if possible, please share the DWSIM file with us at contact-dwsim@fossee.in.
