Great, thank you very much Daniel - not sure if my coding skills are up to it, but I will give it a go! Looking forwards to seeing the update. Regards, Cameron

Hi Daniel, I hope you are doing well. I was wondering if you could answer a question regarding a custom unit-operation I have developed in python.net. I calculate some profiles for the unit and now want to be able to use ‘Insert<Chart’ in order to produce a graph of some of said profiles, such that is observable in the flowsheet (as you can with the normal unit operations). I see that, naturally, when I select my custom unit operation, none of my data sets can be chosen in the drop-down menu. Is...

Hi Daniel, Thanks so much for your help. I think, unfortunately, I am again limited by my M1 mac as DWSIM appears unable to use the python on my mac :(. Thanks again for looking at this though. Cameron

Hi Daniel, Really enjoying using DWSIM. I have made some ironpython scripts for some custom unit operations, and am now looking to use python.net such that I can use modules like numpy. However, when I try python.net, I get the errror 'Python.Runtime.UcsMarshaler' Threw an exception. Would you be able to provide any help on this? Best, Cameron

Hi, When I install the Neural Network Unit operation, I can't seem to 'drag and drop' it into my flowsheet. I can see 'Neural Network (Pro)' under user models, but it can't be brought onto the flowsheet. I installed the file from this link https://danwbr.gumroad.com/l/FTdVs. Thanks, Cameron

Is there anything that I can do in order to avoid this issue?

Hi, I am going through the tutorial for creating a neural network in DWSIM and have run into some issues. Firstly, whenever I used the .xslx file, the simulation would crash when trying to import the data, so I resorted to .csv which worked fine. Secondly, whenever I try to train the model, DWSIM crashes. I have attatched the errolog.
