Ventana software support forum

PS. Vensim has a dark mode sketch if you want to use it (View->Dark mode sketch).

Thank you.

Does it work ok if you press SHIFT and delete?

Yes. Create an unchangeable constant called "kg per lb", give it the correct units (kg/lb) and value (0.453592). Then you can use it to convert any kg or lb measurements in your model.

All you should do is save your model. It should not appear once you have saved.

Have you recently updated MacOS?

Are you on Mac or Windows?

I'm struggling to follow at what you are doing here. Subscripts are usually used to turn one variable into an array. So you could have a variable called "sales" and this could be subscripted by "region". I've had a go at building something simple that I think might be what you ar...

The lookup would almost certainly be faster.

Do you have a timeline for retiring Venapps and introducing web publishing? We have a client that needs a flight simulator in Q2 2024 (preferably April vs June) and web would be a much better solution. You can already publish to the web via Vensim DSS. This gives you a model that will happily run i...

I'm currently travelling so don't have a computer in front of me. It's to the left of where you enter the run name. It should also have a tool tip, so hold the mouse over each button until you find it.

It's still there along the top toolbar, but with more functionality now.

The FIND ZERO function should do what you need. It can loop a section of model structure to try and numerically solve something. There is an example in the help system on how to use it (I'm travelling otherwise I would have pasted the link for you).

Seems to be a common problem when I search Google. Have you changed a printer recently or updated anything?

Mac or Windows?

I've never heard of anything like this happening before, and cannot think why it would.

I've just had a quick search, the two links I clicked suggested other things.

There is a lot of info on Google about this, have you tried following some of those suggestions?

These are too old to be of any use these days. They are for converting models that are over 20 years old.

Can you provide more detail on what you are trying to do please?

Sorry, I do not know what you are asking for help with.

Venapps are not very flexible, all you can really do is add textonly for each line of the paragraph.

I right-click on arrow, click on courier which is the default and change size to 19. Nothing happens.
Any ideas what i do wrong here?

We know about this. Try setting it a 2nd time and it should work.

You can define sub-ranges. For example

EUROPEAN COUNTRIES : ENGLAND, SCOTLAND, WALES, NORTHERN IRELAND, FRANCE
NON EURO COUNTRIES : USA, CANADA

COUNTRIES : EUROPEAN COUNTRIES, NON EURO COUNTRIES

Is this what you need to do?

You haven't provided much information, so I'll guess.

Assuming you have a value that ranges between 0-1, create a new variable and plot that.

some variable = 0.5

some variable percent = 0.5 * 100

You cannot set the initial population to be a time series, it's an initial value, so a constant. But I think the following will do what you need. population = INTEG(birth-death, initial population) population used before projections start = if then else ( time < 2023, historical pop, population). No...

There are a number of random distributions available in Vensim.

You cannot run the old interface on MacOS Sonoma.
