Re: Best practice to avoid data warnings?

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 model. The go...

Re: Best practice to avoid data warnings?

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...

Best practice to avoid data warnings?

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: No data found ...

Re: Loading Data, Constants, Lookups from .csv files in WebAssembly

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.

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

Re: How can I run a Vensim game over the web?

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...

XMILE Model Error dialog box is unhelpful

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 even know whe...

BUG: XMILE file crashes upon opening

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.

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.

Resizing the subscripts window, so it is larger and more useable, causes the window to become blank.

We've also had crashes in Windows 10. This thread looks like a specific issue, and we can't narrow our situation down. Often it happens when in SyntheSim mode in and trying to hunt down behavior in a large model.

Re: BUG: Vensim (macOS) Need to implement Hide

You might not be trying to follow official guidelines like a good macOS app, but it should be easy to capture a keystroke and call the correct command. It can be platform specific code that is #ifdef'd if needed. Doable if you want to spend the time.
