Hello. I am having a problem trying to use the CAPE Open Unit Operation. Using version 8.23, Peng Robinson, and Thermodynamic properties from Chemsep. The main objective is to simulate a extractive distillation column for Benzene-Acetonitile-DMSO system using Wilson Activity coeff. When I try to solve the column it gives me an error HRESULT 0x80040501. Please suggest appropriate solution.
