Great. Thank you, both, for the clarifications.

Tom – Could you post an example of a GET DATA request that is and is not wrapped by INITIAL? Maybe just screenshots the two equation editor windows showing the difference? I think the model I'm working on might benefit from this.

Thanks in advance.

It seems like all the paths should call the same Vensim function, though, and that should handle all the windowing in Vensim the same. The four code paths seem to differ too early in the opening process. I assume that each of the four paths should all do the following steps: String model_path = SPEC...

Well, I"m Zoomed at 100% in this model. Admin – it is the Energy Policy Simulator model. You likely have it already, but you can download a version here (Note: I'm using v3.3 and v3.4, but I'm sure v4 is the same): https://github.com/EnergyInnovation/eps-us/archive/refs/tags/4.0.3.zip The Web A...

Double-clicking mostly. Maybe even cmd-O in the Finder.

So two different behaviors (meaning two different code paths) depending on how a file is opened? That is confusing for users (ie. Me!).

I agree -- it is not this system-wide setting. Normally the scrollbars in Vensim are always showing but sometimes they disappear. It might be after a do a lot of right-click-grab-canvas scrolling, but I'm not certain. It might also be after switching views.

I open a MDL, change views, and there aren't scrollbars any more. This is for a very big view. I can quit Vensim and reopen and then they will appear again.

I have the setting to Close Active Model turned off. I used to be able to open multiple files. This doesn't seem to work any more. Not sure when it broke, but I think this was working several months ago.

VensimDSSMC v10.2.1 seems more sluggish in the last fews months. This is both for me and a colleague. We don't know if it is a Vensim update or maybe related to the release of macOS15 Sequoia. We're scrolling through some pretty big views with embedded graphs and lots of variables. It was always lab...

Oh, I didn't know about the setting. A quick spot check of my models shows that 'strict' is off, which I assume is the default.

I’m not sure I follow your question but I think “strict” is the answer. “Percent” is a unit like “dollar” and Vensim applies normal units checking.

I do something similar to Tom, including a constant model variable for conversion so the units pass the unit check. To draw out something Tom eluded to, please name your model's variables appropriately. If the value is 0-1, then it should be "Fraction of Population that Loves Pizza". If is...

I clicked on the Zoom tool in the lower right corner of the window to get the following dialog. I must have hit delete (to blank out the text field) and then tried typing a new percentage. I just get beeps and no typing. Work around: use the up/down arrow to repopulate the text field and then the fi...

The OP was right that SDEverywhere [sdeverywhere.org] does have functionality to track changes across model evolution. It is really powerful. I'll give a short summary here. MODEL COMPARE * when you build a model, you can save off a version that is the version to compare to. Sometimes you think of t...

I have a table with the following definition (defined in the GUI) :TABLE CPL_2035_Summary :TITLE 2035 Metrics :PRINT-EVERY 5 :X-MIN 2025 :X-MAX 2050 :FONT Arial Unicode MS|12||0-0-0 :VAR CPL Carbon Tax Rate 2019[Sectors] :DATASET :VAR Output Total CH4 Emissions :DATASET :VAR Output Total CO2e Emissi...

I was wondering about messing with scroll/zoom settings but I then thought that "the current system messes with it already." I might be wrong though. If you're working in a model that has 20 views that are all Very Big at 100% (not fit on a screen), doesn't the current F3 Find behavior cha...

I often use Find and F3 to find again. That is, I want to see when a variable is used and it is often on multiple views. The current behavior of Vensim is to change the view and highlight the variable *somewhere* on the screen. I spend the next few second trying to find the variable. Often it is in ...

Passing on information relevant for Vensim users: SDEverywhere, a tool for MDL files to automate testing and publish web apps, got a big update in August 2024. [https://sdeverywhere.org] One of the biggest additions is an improved ease of installation and use by removing the need for Emscripten. The...

ReadSDR is a good suggestion. An alternative that is likely more complicated would be to use SDEverywhere [https://sdeverywhere.org] to convert to C code. I'm pretty sure you can call C code from R. Or SDEverywhere also has the ability to run models from a command line (Terminal), which you might be...

Yes, this one is definitely weird. I don't want to make this too broad of an issue, but the windowing on macOS has always been a bit whacky. Something that has been raised in the past (either conversation or maybe another forum thread) is that "focus" isn't handled as expected on the platf...

We were editing CIN files and CMD files in Visual Studio Code and, after adding some comments in the CIN file, were wondering about syntax coloring. Has anyone developed a VSCode extension and/or grammars or anything related to syntax coloring for Vensim and/or SD-related files (e.g., XMILE)? More i...

Another bit of strange behavior with two displays, but not exactly related to the disappearing window: I'm working on an external monitor with my laptop open (as opposed to two external displays with laptop closed, as above). The main Vensim window is on the external display. When I select a variabl...

I'm working with two displays. To take advantage of the screen real estate, I decided undock the Control Panel window and move it to the second display. I used the following steps: 1. Use the mouse to grab the top part of the docked palette and started dragging. 2. As soon as I passed into the secon...

Agree - this looks really useful!

Is there any reason to not run MC all the time, even if you're not doing sensitivity runs? And, assuming it is fine, I'm kinda wondering why there are two builds of Vensim then. Will you just be releasing the MC version as plain "Vensim" in the future? (<---leading question....). ;-) I'm a...
