This is correct (it's mentioned in the help system that the min/max etc must be numbers).

It's impossible to offer any advice without a model to look at.

What version of Vensim are you using and on Mac or Windows?

I've just tried this on the latest version and it seems fine.

At the foot of the page, it details where you can find them on your computer. The location of the Models directory varies by platform. Normally the full path for this directory is •c:\Documents and Settings\All Users\Vensim\Models (Windows XP), •c:\Users\Public\Vensim\Models (Windows Vista/7/8/10/11...

I don't think it actually matters. During development we used the 32 bit version, but I'm sure 64 bit will work fine too.

Create a custom graph, add two variables and make sure you do not click the "Inherit scale" checkbox for the 2nd variable.

You will need to upload the model.

It's either division by zero, or one of your variables is exponentially growing. Impossible to say without seeing the model.

This fires up the command script successfully for me (run from a terminal prompt)

/Applications/VensimDSS.app/Contents/MacOS/VensimDSS /Users/tony/Downloads/TravisForumProblem/SampleCMDScript.cmd

What happens if you turn off

Are you on Mac or Windows?

Take a look at the following page, it details exactly where to find the models on Mac/Windows.

Looking in more detail at this, if you move the variable attached to the flow, it does move to the correct place. The next release will have this fixed.

All in the help system including examples.

It's available with Vensim.

On Windows, you should find it in
C:\Users\Public\Vensim\Models\Sample\WRLD3-03

You could also consider a queue instead as you can remove things from one of those.

I'd start by removing "people quitting" and thinking about implementing it in a different way. The equation is too complex for that anyway. As you are directly delaying "People to train" to calculate "People trained", if you do have people quitting, "Training"...

It's not in Vensim PLE.

No, there are hundreds of places in Vensim where you can select text, that's why I asked for more info.

1. Does your model pass the units test?

2. Have you selected an appropriate time step? https://www.vensim.com/documentation/ref_time_step.html

It's impossible to comment further without the model.

Can you provide more detail please? Where are you clicking things? Can you give an example?

We'll get this fixed as soon as possible.

8.0.0 does not even run on modern Macs, you are best off using the latest version.

To give you a little more help, try this burning of coal = min ( available coal resources / time step , base burning rate ) This equation burns the "base burning rate" until all the "available coal resources" are used up. This equation takes "base burning rate" from the...

You do have units errors in your model.

Start with "base burning rate". That should not be measured in 1/year, I'm pretty certain it will be tonnes/year. Same for "base discovery rate". Correct the units for these, and you'll see where the error is.

All I did was put the graph onto the sketch using the IO tool.

Try the attached.
