Ventana software support forum

I've seen this on the Mac, and I'm not sure why it doesn't wait (it should).

An email address would be great, if it's a problem we haven't seen before, I can then get in touch.

Almost certainly a permissions issue. You'll need to search the web for how to allow an application on MacOS access folders.

Your only option is to load it into a lookup table. Vensim PLE does not support external data.

If you can email the model to us, we may be able to get it to load.

No. Even for small models, the number of loops can run into millions.

Your profile says you are a PLE user, the DLL does not come with PLE.

Or did you get the DLL from somewhere else?

Your path to the DLL is wrong. Why did you move the DLL to "c:\program files (x86)\vensim"?

I think the sample model is a poor demonstration of the function. I'll replace it in the near future.

It's a bug, and will be fixed in the next release.

Yes, we'll get this fixed.

No, you cannot switch the app itself into light mode. You can switch the sketch though (under the view menu).

You could try

We've done it twice in the past. Way back (25 years ago), I implemented the simplex code from numerical recipes. And I know Tom wrote code a few years ago include LP Solve in Vensim. Both efforts were via external functions. What we have is certainly out of date by now. I'll create a ticket in our i...

I'm guessing you are using a relatively small display. Try a point size of 9, then 10, then 11 and see if that helps.

And how large is your display? What is the resolution?

What point size have you selected for the font?

Try making the font smaller.

Vensim tests to see if the editor can fit on screen when it's started. If it cannot, it reverts to a small size, so it's likely the font you've selected is too large.

This will change when we enable the new editor (coming soon).

This is working fine for me.

Are you using a file sync application at all? Maybe the .c file that Vensim creates is being marked as in use?

ok, I'll test. Hopefully it's something very simple like a permissions issue.

Always check the return value when calling into the DLL, if it returns zero, something has not worked correctly. For example, you are not checking the result of the call
vensim_dll.vensim_get_vecvals(vec.ctypes.data_as(POINTER(c_float)), fp, len(Variable))

You can also use sub-models if you want to include an existing model in a new one.

Yes, you can just copy/paste.

Make sure you have Tools->Options->General, "Close active model on open/new" unticked.

I'm not sure if you need a lookup.

Can you explain the relationship between "Vacancies" and "number of active workers"?

For the control panel, if I toggle it on/off again, it appears back on the main screen.

Hmm. This is bizarre.

If I move the Vensim main window onto the other monitor, the dialog re-appears.

I'll need time to investigate this.
