Ventana software support forum

I am facing a similar issue, and since the solution was not discussed here, I'm bringing up this post. I have been running a script over the past few months to run a cmd file, but now (I think after updating Vensim or macOS), I get the same error. I can run Vensim (not even the model) to run the cmd...

I just randomly found out that the custom graphs window (at least on macOS) has been updated, and there are a lot of useful features (like formatting options) easily accessible. When I saw this, I intuitively dragged and dropped the custom graph from the list, and it added the graph to the interface...

Shouldn't there be a 'dot' before the file path? Like "./full/path/in/quotes/script.cmd"?

Thank you very much, Tom! ':COMSYS' worked. So did the spaces between lines. This is exactly what I was looking for. Thanks again.

This is what I meant by the shortcuts. macOS has this option that users can define shortcuts for the items in the menu bar, which can be app specific. For example, I have defined a shortcut for import dataset because I use it a lot when I am debugging my applied models. Then, I don't have to use the...

Is it possible to add comments to the VOC file without breaking it? Also, is space between the lines allowed?

I am calibrating a large model with a lot of parameters. I want to use comments to categorize and organize them. I appreciate any best practices you might want to share.

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.
