11. ‘Suppress simulation information window’ does not suppress the information window then the model is reading a CIN file or other inputs to constants (like .out files). In the settings, there is even an option to suppress errors, so it would be beneficial to make this optional too. Reading changes...

8. I’d appreciate if you could make the ‘dark mode sketch’ to be enabled automatically but include an option like Microsoft Office apps to customize that behavior Turn off Dark Mode.png 9. The table in the dark mode has a white background Time (Year).png 10. The graph legends in the dark mode have w...

A few other issues: 1. I have a 14-inch MacBook and I think this window was designed on a larger display because every time I have to resize it to get to the ‘Simulate’ button. The window size is restarted every time I close it. Screenshot 2024-05-02 at 10.04.30 AM.png 2. The tools in the analysis t...

Now that Vensim is available on Apple Silicon, I think it should be able to run on iPad Pros with the same chip (identical architecture).

I think RK methods calculate intermediate points and evaluate the function at these points before determining the state at the next timestep. If the threshold condition changes within a timestep, RK might miss the exact point of change because it's looking at the function at intermediate points (not...

Also, if I remember it correctly, ''MENU>EXIT'' does not exist on macOS.

Thank you so much for fixing this issue in the new release. Everything is very smooth now. Thanks again!

I see. Sorry about the confusion. I quickly checked, and it seems this happens everywhere. However, all the modern interfaces only include ‘.’ and ‘_’ in the double-click selection. Even Vensim on macOS follows the same rule.

Here are the screenshots of Vensim and Windows Notepad when double-clicking the same string. Did you have something else in mind?

On Windows, could you please change the double-click selection behavior to select only text-related characters and not the adjacent mathematical symbols like +, *, /, [], ()?

Thanks a lot! It can also happen when subscripts are defined incorrectly.

Does this work?

When there are issues with the subscripts defined in the Vensim Optimization Control (.voc) file, Vensim reports 'ERROR: Problems encountered in the simulation.' when running the optimizer. It would be helpful if more targeted information is provided when this error is shown.

Thank you very much.

Is it possible to use the Unix time in a Vensim model?

My account is not the system administrator on the PC, and I cannot access the admin permissions. But the admin installed Vensim, so I assume they used ‘Run as Administrator.’ I see my user account and the admin’s separately. On my laptop (windows), I tried using the same account (with admin permissi...

The DLL folder and its content is in C:\Users\Public\Vensim\DLL and the vendll64.dll is in system32 folder. I've checked multiple times and I am sure I've installed the correct version of VenPy (the one pointing to vendll64.dll) and verified the installation.

I get this error when I run my script to use Vensim DLL. I have attached the VRF file, and I would appreciate it if you could help me with this.

I get the same error when running VenPy/DLL. Since I'm on en10010300 (DSS) that file doesn't seem to be working. Can you please help me with that?

I'm just saving the data I need. It's more than a hundred thousand simulations; even with save per 1, it's millions of data points.

I don't mind waiting if it is in the order of a few days. But sometimes, Vensim returns 3221226505 instead of 0 and that's why I was suspicious of the file size. So I guess it might have been successfully completed in the first place.

I’m trying to export sensitivity .vdfx file to .tab. Is there a limit on the file size of that Vensim can handle? I’m using a command script within a python workflow on windows and so far it can’t go beyond 5 GB .tab when exporting a 1 GB vdfx. Everything is done locally (no Dropbox) and I’ve tried ...

What is the equivalent of 'MENU>EXIT' command in macOS?

I just want to remind you about this unusual behavior where a new window pops up when I open a model by double-clicking it.

Just to share my experience: I use a virtual machine on macOS. For such tasks, I Print to PDF on Windows and use the output on macOs. I import the PDF in MS Powerpoint or even MS Word as image and crop the extra parts. But l'm not sure about the advantages of one method over the other.

The option is disabled whenever I close the 'Options...' window. I'm on Windows 11 and Vensim DSS 10.1.3(MC).
