Ventana software support forum

Do the models that failed still fail? Were they working in other applications?

I'm asking to get a sense of Vensim's XMILE support today and support in the future. If there are known issues it would be great to understand them better.

Which models did you have that failed? Do they work now? Do you want me to see if they are valid in other tools?

Ventana/Admin – A pointer, in case you didn't know about this: There are GitHub repositories for sample models that try to help with reference implementations. You can find them in the test-models repo of SDX (SD Exchange, I think it stood for) https://github.com/SDXorg/ . Currently there are lots o...

If Stella doesn't conform to the standard, you should tell them. Did you reach out to them when there was a problem? They have been supportive of the XMILE file format and the standards working group, so I think they would fix something. Also, several other tools use the XMILE standard and seem inte...

Unfortunately, even though they should be in Xmile format, they rarely are.

Curious: what do you mean they aren't in the Xmile format? Do you mean they aren't XML or something else?

My main goal in this Vensim-focused forum was to help with your original question about publishing SD models to the web and helping you think through different tools. I would have negligent not to mention Stella Architect as an option. Vensim also have some built-in web app tools but I haven't used ...

Yeah currently all the tools have some learning curve. The easiest tool might be Stella Architect right now, since their web tools are integrated into Stella (visual web page design, kinda like Forio) and they also have a way to upload your model so it is hosted on the web. Basically a whole package...

Forio probably has a gentler learning curve (been a while since I used it) but you might learn more about SDE's default web app UI. SDE should allow someone to define the variables they want to graph and define the variables they want to be sliders (in a table, like XLS), and then do all the rest of...

Is there functionality to within Vensim to "Fit onto one page" still? This was a feature in the print window but I don't see it now. Seems like Vensim use to do some scaling before handing it to the print driver but now it doesn't. I've adjusted the print driving (macOS) in several ways bu...

There is SDEverywhere, which is basically designed to publish SD models to the web. It does more, like compiling to C and WASM, and also unit testing and other features that make it possible to have a continuous integration workflow when building a model. SDEverywhere is free, open source, and able ...

I can confirm it is working for me too. I had to `chmod +x` the scripts in the zip file above. I also changed the group ownership, but I think the +x was the key issue.

Glad we figured this out and it wasn't the certificate signing issue!

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...
