I agree that what I would like is a general purpose environments. But after testing quite a long list of software, the only one that works as intended is Simulink. But for commercial reasons, I need to move away from it. In an ideal world, I would like Simulink for python, but such app does not exist yet, only some barebones abandoned projects which looked promising. I do disagree with you that DWSIM is only worth due to its chemical process abilities. Like I said, general purpose modelling/process...

That sounds like a solution. Creating a dummy property package that only enforces a set of compounds/properties, but no thermodynamics/relationships between them. Could you point me in the direction of doing this?

Would it be possible to configure DWSIM in a way that it does not enforce any minimum set of units, compounds or thermodynamic packages? I am looking to move away from Simulink, which gives me the freedom to run simulations only with choosing the sequentials scripts I need. We currently have a series of python and/or matlab scripts which contain certain design models (not dynamic), so therefore running them in a flowsheeting environment (such as DWSIM) would be great. Thanks in advance!

I guess system of units. I need to define certain variables that are used un WW, such as COD, BOD, TKN, etc.

Hola! I´m in a very tedious process of trying to streamling the use of many many existing excel spreadsheets that we use for designing wastewater systems. As much as i hate it, for now I think the easiest would be to define excel unit ops for every process to later create the flowsheet and chain them in dwsim. I have been trying to get the excel built in unit to work for this, but my main issue is that I cannot seem to change the strict rules in which it uses units: The main properties have to be...
