Hello, I have a Python script that iteratively computes permeate and retentate flows for a membrane separation unit. When I run this code in a Jupyter Notebook—where all variables (total flow, pressure, membrane area/thickness, permeabilities, etc.) are defined directly—it executes flawlessly and produces the expected membrane separation results. However, when I paste the same code into DWSIM’s Python Script Unit Operation, it immediately throws an Index was outside the bounds of the array error....
