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: [code] /Applications/VensimDSS.app/Contents/MacOS/VensimDSS "/full/path/in/quotes/script.cmd" [/code] 3. Vensim opens...

Does this work on Windows? Is this a macOS problem? We'd love to have a workflow that runs the model and exports the data, but can't get by this step.

I tried removing the LST file from the line and now the error message says, "Unable to open BAU.vdfx to read data." Could it be some path issue?

Aside: Is there a way to add comments to CMD files? "#" at the beginning of a line or something like that? This would be a nice feature, to comment code and/or comment command lines.

I ran that single line in a new CMD file. Vensim opened with an error dialog what said, "Unable to open SaveList.lst to read variable names."

The LST file is in the same directory as the CMD, MDL, and VDFX files.

Should the following script work to export to XLSX? When I call it Vensim opens but then quickly closes. All the files are in the same directory. A XLSX file with the same name does already exist (and I'd like this script to always replace it). [code] SPECIAL>NOINTERACTION MENU>VDF2XLSX|BAU.vdfx|BAU...

Btw, I (still) feel that a user should be able to close all the model windows in Vensim macOS. When I close the model I'm currently working on (single model open), currently a new model window is opened. I can't think of any other app on macOS what works like that. In Word and Safari, etc., I can cl...

Updated to 10.1.5.

This seems fixed. Thank you.

Updated to 10.1.5.

This is still a problem.

I have the Settings "Close active model on New/Open" turned off. But, when I double-click on a second MDL file it replaces the currently opened model that I'm working on. Expected behavior would be to open a new window with the second model, given the current Setting choice. Vensim 10.1.2 ...

BUG: Double-clicking an MDL file in Finder still open a new model window Steps to reproduce: 1. in macOS Finder, double-click on a model.mdl file. 2. Vensim opens the model, but also opens a blank new model window. 3. This new model window covers the desired model's window, and makes it look like th...

Yeah, I'm not getting Vensim to quit/close at the end of my script, so I think MENU>EXIT is not working.

Quick aside: Is there a way to comment a line in a CMD file? I tried # but that gave an error. I don't see any comments in the examples.

Ah, that is definitely a different way at calling the script. I shouldn't use the "open -a..." command from Terminal. Just call the Vensim binary directly with "/Applications/VensimDSS.app/Contents/MacOS/VensimDSS". I got my first script to work now. Please update the documentati...

I can't get a command script to work on macOS 14.4.1 with VensimDSS 10.1.2. [code] SPECIAL>NOINTERACTION #SPECIAL>LOADMODEL|model.mdl MENU>VDF2XLSX|BAU.vdfx|BAU.xlsx|SaveListForGraphs.lst MENU>EXIT [/code] The command script, the MDL, LST, and VDFX are all in the same directory. I've made sure there...

Admin – Does Vensim run on Big Sur version 11.x still? I remember another thread where some people where having trouble with older version of macOS. Maybe Nicole should also consider updating macOS?

But the hidden file is the first thing to check...

Also, a great way to put Vensim models on the web is SDEverywhere (sdeverywhere.org). An open source project that is used by several big models, including En-ROADS (www.En-ROADS.org).

SDE has been developed and used for approx 8 years. Tested and still under development.

@nicole - what model of MacBook Air do you have?

@mallari - thanks. Since your computer is pretty recent, I would suggest upgrading your version of macOS. Many developers support the current version (now 14) and maybe the previous two (12, 13). Ventana is doing a good job finding a solution for you, but you might start running into other software ...

@mallari_cristina I'm glad it works now. What computer are you using? Could you tell us the model, year, and processor CPU?

This makes sense. Thanks for the explanation. If I can be helpful in thinking through the UI/UX, let me know.

I understand the admin's point of view, but I'll try to represent a new user's perspective. Vensim is a very complex and daunting tool. Decimals create a cognitive load (for anyone) and scare students (and sometimes modelers). If Vensim can help a user by only displaying complexity and precision whe...

Robbie – this might not help you given how far along you are, but SDEverywhere includes performance measurement as part of its quality control tools. One way this has been used is to compare the performance of one version of the model with another. Sometimes this helps catch performance degradation ...

Huh, I don't remember this level of precision in previous version of Vensim (e.g., v8). I would suggest limiting this since it isn't helpful for the user and is particularly weird when time is years, like this: [attachment=0]Screenshot 2023-10-31 at 3.29.56 PM.png[/attachment] Seems like it should b...

I don't remember this before, but it seems you can't have integer values for a model's INITIAL TIME or FINAL TIME. Or, at least, the formatters for the Model Settings window don't let you. I've tried removing the extraneous zeros but they always come back. Several models, not just one. Vensim 10.1, ...
