Ventana software support forum

Tab control. Create as many tabs as you want using the properties page. Then select the tab and drop controls on it in the same way you do any screen. Each tab is like an embedded mini screen. To name a run, create a button, and execute the venapp command SIMULATE>RUNNAME|? To load/unload runs, crea...

Are you running Vensim PLE? If yes, optimization is not available to you.

What is LUVar?

The easiest thing is to avoid "auxiliary with lookup". If LUVar is a time series, you would use something like

Can you post the code so we can take a look? Maybe we can spot something.

I've had a quick Google for sectors.

In Vensim, you would do each sector on a different view.

Before you do anything else, add units to every parameter in the model and make sure it passed the units check. If you start introducing yearly data you will most likely get errors in your model which the units check will pick up. Once this is done, upload the model and we will be able to help. Tony.

I really do not understand what the 2nd problem is. You mention that you run it until 2014 and it shows the results, that is what it should do.

Did you use the screen I uploaded to only allow the setting of the slider once?

Thanks. Sorry for the hassle, we've spent a long time in the past helping users who have acquired Vensim illegally. I'll have to read up on eignevalues/vectors so will not get the chance to do this till Monday. Maybe Tom might will visit the forum later, he might know the answer without having to re...

Can you fill in the serial number of your licence on your profile correctly please and we will be more than happy to help.

Tony.

ok, the thousands is easy, see Image1.jpg Can you give me instructions on how to get to the 2nd problem (what do I click to get the error to appear)? 3rd problem. Create a directory called "Scripts" in your project directory. Save the file extprog.vst in there. Now load up the screen that ...

Can you upload the screens you are trying to modify and I'll take a look?

Use either the MIN or MAX functions. The syntax is

Make sure the autosize rows format command comes before the insert separator. The separator is sized correctly, but then the autosize changes things.

I don't understand what you mean. Can you send me the screen (just the VNN, I do not need the whole project)?

How about something like R1 = RANDOM UNIFORM() R2 = RANDOM UNIFORM() R3 = RANDOM UNIFORM() R4 = RANDOM UNIFORM() TOTAL RANDOM = R1 + R2 + R3 + R4 R1 share = R1 / TOTAL RANDOM R2 share = R2 / TOTAL RANDOM R3 share = R3 / TOTAL RANDOM R4 share = R4 / TOTAL RANDOM This is much easier when using subscri...

I would try to avoid it where possible as it can make things tricky to debug. There are two ways. Either embed them result = IF THEN ELSE ( a > b , c , IF THEN ELSE ( a > d , e, 0 ) ) or add them (this is my preferred option as I find it clearer). result = IF THEN ELSE ( a > b , c , 0 ) + IF THEN EL...

ok, it looks like the graph component has not installed properly (the hollow window should show something).

Can you try reinstalling?

Everything seems fine to me.

Can you explain exactly what you are doing step by step? I mean what buttons you press etc and I'll take the same steps here to try and recreate the problem.

When you insert the graph, do you see a blank graph at all? Or just a hollow box?

Tony.

I can view the properties ok. Are you selecting a certain property or tab?

What version of Sable are you using?

And do you get a graph appearing on the screen at all, or does it crash immediately?

Do you have any experience of programming? If yes, you should be able to figure out what the error is here. If you do not have any experience of programming, it would be a good idea to search around Google for a tutorial. The following is the reason things are not working for you. But as I said, if ...

This should work.

You can go more than 8785 time steps.

What problem are you having?

It sounds like something has gone wrong with the permissions on your machine. Unfortunately I cannot offer any advice on the Mac (I only use it when testing Vensim). I do know that there is a "fix permissions" setting somewhere on the Mac, you could try that.

And if you open it, does it install ok?

That is just a standard Mac warning message to make sure you don't run any programs you don't want to. It's not an error with the documentation.
