Re: Unit : It is possible to have (k*pas) *(k*km) = M*km*pas

You would usually have something like
- passengers
------> Value = 12
------> Unit = kpas

and

- distanceMean
------> Value = 3
------> Unit = kkm

and I multiply them, to get :

- mobility
------> Value = 36
------> Unit = kpas*kkm

Re: BUG: Mac Vensim 8 output windows have black text in dark mode

I think the way forward for dark mode is to have two different initialisation files, one for normal and one for dark. You can change the output font for the table/graph/stats etc. But what one person likes does not always match with what others want. I'll look into having two initialisation files, t...

Thanks, this should be straightforward to implement as we already change some of the icons when in dark mode.

Re: vensim .mdl extension applied to flight sim files

There really is no need to delete Vensim from the computer. All you need to do is use the shortcut to start it rather than double clicking on the model.

Re: vensim .mdl extension applied to flight sim files

You can only have one application associated with MDL files. But that doesn't really matter. Don't double click the files. If it's a Vensim model, start Vensim using the shortcut to it, then click File->Open and browse to the model. I'm not familiar with the flight sim, but there must be a similar w...

Re: Can't download the free Vensim in my Mac (OS 10.14.5)

Search the web for help on this.

The latest versions of Vensim are fully digitally signed and notarized by Apple, so if you are seeing this, it suggests their service is down, or some other issue with your computer.

Re: vensim .mdl extension applied to flight sim files

My guess is that you are double clicking on a MDL file, and this is starting up the wrong application (flight sim instead of Vensim?). All I can suggest is starting the application via it's shortcut, then using File->Open to open the correct file. The other alternative is to register MDL files as us...

Re: New User (Graduate Engineering Student) Modeling/Software Issues with Real Time Experiment

Instead of having "INITIAL AREA", call it AREA, make it a level, and drain it over time.

It might also be a good idea to visit

On this page you will find a really good Vensim PLE tutorial which will cover basics like this.

Re: How to run sensitivity simulations with Vensim DLL

Try putting those commands into a CMD file and running them as a command script using Vensim DSS. It might show you where the error is.
2. How can the run name be specified as well for the sensitivity simulation (for the resulting .vdf file)?
Use SIMULATE>RUNNAME|filename

Re: Problem getting 0 if value is below 0

The "/2" was necessary, because otherwise Old["1"] - New["1"] would be (-7) - 7 = -14. So divided by 2 it'll get you the -7 busses you want to decrease. You really do not want to divide here by 2. The stock should only have inflows and outflows, what you've got half of the inflows/outflows. If you ...

The Mac version is a port of the Windows code, so we are not following any Apple guidelines.

Re: FR: Implement auto update feature

We do give the user the option to be notified of updates via the download centre. You can also hit Help->Newer Releases to get access to them.

I'm not sure of the legality of pushing updates onto users especially now with the new GDPR regulations.
