Ventana software support forum

Sorry for the slow reply.

Can you email/upload the config you are using? I've tried experimenting here and am not seeing the same behaviour you are (Vensim freezing).

The simplest would be to introduce another stock to represent the waiting period.

Also try the check syntax button in the editor.

Try adding time to the sketch using the shadow variable tool <V>. Then draw an arrow from time to your auxiliary. Does that fix things ?

That looks correct to me.

What is the syntax error?

Venapps might still work in the old GUI. We found that so few people use them, we concentrated on a more usable option in the newest version of Vensim (GUI objects directly on the sketch).

SyntheSim is available in the model reader.

Can you give us an example model (or just the sketch)?

I'd urge you to use SVG instead if you can. I'm sure it will not be long before SVG is a recognized clipboard format.

GET XLS is not supported yet (we are working on that though, it requires a lot more code to be migrated).

Thanks for the note about POWER, I'll fix that.

You've got the "initial" value set to a pulse train. The initial value is used to initialize the stock, not increase it during a simulation. Create a new variable called "yearly inflow" (or something better), make the equation PULSE TRAIN (0,0.01,1,8). Now in your equation above,...

Would PULSE TRAIN do what you need? That can be used to introduce a fixed amount at various intervals.

The same thing works for loops/causal chains as well.

I thought you could drag/drop from the error panel onto the sketch, but I must have missed adding that functionality in.

No, it does not change the calculation. But units errors should be fixed, they indicate an error in logic in your equations.

This is why they are important, https://www.bbc.co.uk/news/magazine-27509559

I'll get onto that and produce a demo.

On the sketch toolbar.

We need to update the help system as Venapps have been replaced with GUI objects. More details on them are here. https://www.vensim.com/documentation/user-interface-objects.html Now you add GUI objects to the sketch rather than program a separate user interface. You can also find an example model on...

I've been working on something to address this. I'll prioritise it.

Would IF THEN ELSE do what you need?

Let me experiment as there might not be a way to do this. I'll try though.

It would help if you can reply to this thread and let me know of any other places where the text is not showing up correctly.

The causal table is in 10.1.4, depending on when your maintenance lapsed, you might have access to it. Try logging into the download area (link below) and see if you have access.

I'm not familiar with Kumu, but it sounds like the causal table is probably the tool you need.

Are you sure you cannot get access to that tool? It's been in Vensim for a while, if your licence is still under maintenance you can upgrade to get it.

The email you received when you downloaded PLE contains a link to a tutorial.

No. What kind of thing do you need?

Dark mode still needs work on Windows as I mentioned in the other thread.

I think Tom is referring to GET DATA MIN/GET DATA MAX (https://www.vensim.com/documentation/fn_get_data_min.html?q=GET+DATA+MIN). The GET DATA XLS (etc) functions execute before the rest of the model calculations, and only executes once. The data structures are then populated and used by the simulat...
