Ventana software support forum

Can you provide more details? Maybe we can do something in the user interface so make the solution clearer?

We no longer supply that, you should be able to use vendll32.dll.

Probably X IF MISSING. Data variables are calculated only once before a simulation starts, so if you are running sensitivity/optimization, X IF MISSING will execute once, the IF THEN ELSE will execute every time the model is run.

We should probably add a licence to the models that we developed and ship with Vensim. I'll get onto that.

The world model, I think it's safe to assume that it is in the public domain so you can extend it as you wish.

Click File->New text file to create a CIN file. But I'm not sure this is what you need. Not sure if you are on the latest version of Vensim. Here are some options. 1. Run configurations. Beside the simulate button, you'll see a small triangle. Click this, you can now set up four scenarios and have a...

It's not possible at the moment. I'll ticket it for improvement, as long as the toolkit we use supports it on both Mac/Windows, we should be able to do something.

The commands you need are
SIMULATE>KALMANPAYOFF
SIMULATE>KALMANPARAMETER

Can you provide more detail? What outcomes are you looking at?

And have you selected a suitably small time step?

Option 1 : No, it's not possible in PLE+ either. Only things that actually appear are drawn (for performance reasons), if something is off sketch, effectively it's not there, which is why the tool doesn't work. This will be fixed in the next release.

It's not possible at present. But it is ticketed for improvement.

This will be fixed in the next release.

Are you using the traditional sketch style when right clicking on the valve?

I'll check this and fix if needed when I'm back in front of a computer.

Right click on the valve and you should be able to change the orientation.

Most users stick to the traditional sketch style. The arrows on the "new" style can be difficult to see.

Vensim PLE cannot load .dat files.

You need the SIMULATE>ADDCIN command.

I cannot seem to find a way to do this. I'll fix ASAP.

I'm not familiar with this kind of healthcare so I can only offer some general advice. I think I'd look at the stock of each medicine rather than the demand. Then the outflow from this stock is the "fulfilment rate", but if that cannot be met, try taking any remaining medicine B. That woul...

There is nothing you can do about this in PLE.

We offer some distance courses on our website at

Alternatively you can ask questions directly here.

Yes if using Vensim Pro/DSS.

Right click the table tool icon and edit the settings. Now change the number format.

You need to handle this manually.

First calculate "sales". Then work out what is left (stock - sales * time step), and allocate to other facility.

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 ?
