Re: What improvements would you like to see in Vensim?
I'd like to see an option in the Comment Editor that allows the text in a comment to be included in the documentation. For example, a check box "Document text" to the right of "No cause' so that when selected the comment text appears at the start of the text for a selected comment wh...

No, there is no way to automatically create the stock & flow diagram.

Re: Utilizing Ventana Systems Tools for enhancing data breach protection strategies ?
I've got no doubt that you can use both Vensim and Ventity to help. What you are describing sounds like a major project, it's not something that any of us could give you a few pointers to get you going.

Re: Max file size
Do you really need to export the whole file? You can use a savelist to export just the data you need.

Re: Max file size
In theory there is no maximum file size. It's going to take a lot of time though to export something that size.

Re: Cannot run Vensim after install
From the wiki page,
You should definitely move to Windows 10.Mainstream support for the Embedded Standard edition of Windows 8 ended on July 10, 2018, and extended support ended on July 11, 2023. As of August 2023, 0.35% of PCs are running Windows 8.

Re: Cannot run Vensim after install
I don't think Windows 8 is supported any more so it's unlikely Vensim will run on it.
You can try an older version, or even better, update to a supported operating system.

Re: Export as SVG not workingn correctly for new sketch style
I think that's more or less the best we can do with the newer sketch style.
I'll see if we can adjust things to line up the pipes. But the curves and drop shadows don't seem to be drawn at all.

Re: Unable to converge simultaneous loop
Have you been through any of the Vensim tutorials? I would start with the PLE tutorial at the following page,
http://www.public.asu.edu/~kirkwood/sysdyn/SDRes.htm
This will get you to the point where you can build a basic model. Once you've done this, I'd start again.

Re: How to publish a model using DLLs?
Sorry, I misunderstood your first mesage.
No, you cannot do this via the DLL. The DLL will only open published models, so there is no way to get the MDL file into the DLL in order to publish it. You need to run these commands in Vensim via a command script.

Re: Unable to converge simultaneous loop
You'll need to upload your model for us to be able to help.
It's rare that you even need to use this function, my guess is you have some sort of formulation problem.

Thank you.
This setting is also under the "Excel" settings window, so I'll remove it from the "General" section in the next Vensim release.

Re: Unable to open Vensim
If you've used Vensim before, try deleting or renaming the .venple file in your home folder (it's hidden).
This will mean Vensim starts with default settings, maybe you had the old GUI running before?
