DWSIM - Convergence Error

Convergence Error

Initially the flowsheet is converge with one distillation column. When i insert 2nd distillation column i get the error saying the convergence error. How do i resolve this? Also where can i reset the flowsheet to resimulate it? is there a way to increase the number of iterations?

The number of iterations for the distillation column can be increased under the "General" tab itself against the field "Maximum Number of Iterations". Also, you need not do anything to reset a flowsheet. If you want to re-simulate the flowsheet, click on Solve Flowsheet again and the values are reset to resimulate it.
