If you tell them to make sure they only have one model open, it should be fine.

We'll fix this before the next release (which should be next week).

Actually that's not quite correct, the error occurs if I have more than one model open. I'm investigating.

I'm assuming the graphs are not updating for you?

I can see the same behaviour in this model on a Apple silicon Mac, but it's running fine on an Intel one.

Do you know what version of MacOS your friend is using?

Click Tools->Options then untick "Close active model on open/new".

Can you upload the model or email it to us (vensim@vensim.com)?

The old GUI no longer works on the Mac which is why the option to switch back is gone.

I'm back in the office next Wednesday, so will take a look then (I don't have my Mac with me at the moment).

Not yet. I'm back in the office next Wednesday, so will get to it then (I don't have my Mac with me).

I think we just forgot to add it to the release notes. I'll add it to the next release.

Right now the test is simply the single line script that was suggested. 1. VensimDSS is closed. 2. In Terminal, I call the CMD script using the Vensim app, calling it with: /Applications/VensimDSS.app/Contents/MacOS/VensimDSS "/full/path/in/quotes/script.cmd" 3. Vensim opens and I get the...

How are you using this (step by step please)?

Do you have a model open, then open the CMD script? Or some other way?

Try running "MENU>VDF2XLSX|BAU.vdfx|BAU.xlsx|SaveList.lst|{||||" by itself and see if any error messages appear.

What happens if you use the latest Vensim?

Can you provide more details on exactly you want to do?

If you have PLE+, you can run monte-carlo/sensitivity simulations. This will automatically simulate many times and can sample from various distributions.

Hello, In my model in Vensim I have one subscript StoreID with three different stores as elements. I want to compare what would happen with the stocks and flows in the model if one of these stores is closed. My plan of action would be to remove one of the elements from the active list, so that it w...

Jay Forrester must be turning in his grave at the thought of what is being perpetrated to the System Dynamics. Some of the staff at Ventana were close friends with Jay and worked alongside him right up until he passed away. They are still close to his family. Statements like this can easily be cons...

Also, are you on the latest Vensim?

What email address did you send it to? Nothing has arrived at vensim@vensim.com.

We didn't redefine anything. I don't think I've ever heard anyone referring to a "level and rate diagram". A stock is the same ss a level, and a flow is the same as a rate. Sometimes the term "level" makes more sense than "stock" (eg, water in a reservoir), but they are...

I think we'd need to see the model to get any further with this.

Do you mean monte-carlo simulation? That's in PLE+.

If you want to automate a certain number of runs, you would need DSS.

Thanks Tom, obvious really, confused me completely when I read it.

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. We'll check. 1...

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 We've talked internally about this and decided on the current functionality. We spoke with some teachers that need to review models from...

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. We'll make some tweaks to this for the next release. 2. The tools in the analysis toolset ...
