No, it still doesn't work for me with v10.1. What should I try next?

My "model" and the error message:
[attachment=0]Screenshot 2023-10-03 at 8.16.37 PM.png[/attachment]

I get an error saying that the compilation failed because the model file doesn't exist. I opened the MDL file from within Vensim using the File->Open command. I've changed the Options so that running a "Simulation" requires compilation. I start the simulation using the single-run button in...

I'm interested and trying to help... I haven't look at compiling lately so still getting up to speed... My first question –– and it is likely just outdated documentation –– is that does Vensim expect the dylib to be named? In the "Macx" file the comment suggests that for a model call myMod...

In previous versions of Vensim (v8 and earlier; maybe v9) I found it very powerful to use the star (*) character in the Find dialog. I could type "*tax" and see all the variables with tax in the name. The star character seems to be taken literally now in v10. Was this intentional? Is there...

Related to the this new "single page PDF" question: There used to be a "printed selected variables" and then you could choose to "Fit on one page". Is this functionality gone now? I have a diagram (attached) that currently prints on nine (9) different landscape pages, e...

Agree that a Hiding variable is the way to go when doing this.

Is there a still a way, with the new drawing system, to export a view as a vector image that can be edited easily in PPT (for transitions) or another image editor?

@Robbie what Vensim version are you using? I think source control works best on v9.2 or newer. [edited to v9, no v8]

I like this idea a lot. I don't think F3 finds the *original* variable. Doesn't it find the next use of the variable, which could possibly be another ghost. Going straight to the "definition" would be useful. And if it is a heavily used variable, you could have to press F3 many times to fi...

We have a lot of the four types of errors in my first post above. We do have some "starts before/after", but we also have a lot of the other three types. Stepping back and thinking about the nature of the problem is a good idea. I think this is an issue of sparse data being read into a mod...

I'm inclined not to suppress warnings in development software (Vensim, compilers, etc.) since they are there for a reason. This is under the assumption that they were added to point out something that could be error prone. In that vein, I'm not too keen on the CIN file solution. The CIN file solutio...

When our model is simulated, we're getting quite a few warnings that are data related. This is making seeing other, potentially more useful, warnings difficult. My question is, "What is the best practice for reducing these warnings?" The warnings I'm seeing are similar to: 1."WARNING:...

Picking up on something JohnPW said: I would like to see Vensim situate itself as part of a toolset more. John talked about generic models. Improving workflows of a modern modeler: I envision Vensim fitting in more deeply with many other tools are commonly being used in other modeling, programming a...

Yep -- Todd knows the pain of implementing all the Vensim functions. And I agree that first-party support of model export could be better and is sorely needed. It would have been great if WASM (and full C export) were added to Vensim years ago. The bright side is that SDE is allowing Climate Interac...

Not yet, but that could be added. Right now it would be a hack of some inputs.

But thanks for pointing out Game Mode -- I missed that in the OP.

Jeff -- why aren't you and Todd going with SDEverywhere? Is it not working with your model? It already supports external data files.

I think an easier approach would be to use SDEverywhere. This converts an MDL file to WASM which you could then call. You'll need to do webapp coding to have some web sockets and such, but the model can run locally or on a server (Node.js). SDEverwhere can also generate standalone C code, if that is...

After struggling to import an XMILE formatted model, the imported MDL code has errors. I understand that importing might not always work. But the error reported after Check Model (cmd-T) is simply "Syntax Error". There is nothing actionable with the message. It doesn't help the modeler eve...

I have a working Stella model that I save out to the XMILE file format. macOS Vensim 8.1.1 opens the file and gives an error. Sometimes this causes a crash. One time, after it failed, I tried again and it open (with model errors), but for some reason it did open. Willing to share the model privately.

Sorry -- missed your question. Vensim's new web publishing features are in Vensim 8.1, so make sure you have the latest.

You can find the documentation here: <https://www.vensim.com/documentation/in ... e-inte.htm>

I'd be happy to help you try http://SDEverywhere.org also. We've done quite a bit of work making it fast and able to handle large models. We're actively using it and expanding it, with many performance improvements this summer. SDE already supports external data files. Of course there is Stella, too...

Just double checking: The new table tool can't have time run down, right?

Good question. It is the old Table tool because I like time running down. I would love to use the new table layout with time running down. Also, with the new table tool, it does open in the same place, but it is same place on the non-Vensim display, which is a bit weird given the focus (both window ...

I have two displays. Currently I'm working with Stella on one and Vensim on the other. When I open use the table analysis tool in Vensim, the table window open on the Stella display. I move it to the Vensim display and close it, thinking that maybe it will remember. That doesn't work. I then simply ...

On macOS Catalina, with Vensim 8.1.1: I have a model open. I choose to use the new Sketch view. That closes the current model (I think). I re-open my model. I then close my model (cmd-w). This leave another blank "new model' window. This window doesn't respond to cmd-W. I click the red close-wi...
