Extractive Distillation converging
hello.
I was creating a flowsheet on extractive distillation of benzene and cyclohexane with a mixed entrainer of sulfolane and 0-xylene. For some reason the calculations are not converging. I am a newbie to DWSIM. Can anyone please help me with this

It is difficult to debug the error just by looking at the error message. However, it is understood that the error is because the chemsep column has not converged. Please try selecting a different top and bottoms specification and see if the flowsheet converges.
