Re: Vensim flicks and flips off completely sometimes

ok, I'm getting crashes as well and I know why. The reason is simple. The bottom toolbar in Vensim shows the x and y coordinates of the variable when you click it. But they can only store small numbers and are being overloaded as the view is so large (which causes an exception). The solution would b...

Re: 'Find' command

You can use the F3 button to find the next occurance.

Notepad++ should have been ok, if you can paste in here what Vensim was complaining about I can take a look.

Re: What improvements would you like to see in Vensim?

Our IT staff are wondering if in the long term Vensim could be designed for multithreading, because based on tests we did, seems Vensim is more designed for single-thread processing? Not for a single simulation. It's easy to understand why. For example, to calculate a stock B with an inflow A, you ...

Re: Vensim 8 without single precision?

It's not quite double the memory. It depends on the model and how many variables are being stored, plus how often the values change.

Re: Vensim 8 without single precision?

Correct, single precision is no longer an option. Due to some of the code in Vensim, the 64 bit version of Vensim has to be double precision.

Have you looked at the sample models that ship with Vensim? One of them reads subscripted constants from an Excel sheet.

Re: Vensim DSS 8 x64 DLL Issues

First, start by downloading 8.0.6 which was uploaded yesterday.

Then install using admin permissions (right click on the installer and select "Run as Administrator".

Re: Bug Report: Slider appears in DSS but not in Model Reader for subscripted GET DIRECT CONSTANTS variables

I've just uploaded 8.0.5, this bug should be fixed in it.

To make the sliders appear, run the simulation once using Model->Simulate, and under the changes tab, make sure you tick "Overwrite get...constants" equations. The sliders should now appear ok.

Re: Publish model in VPM format from Vensim 8.04

No, the latest version of Vensim cannot publish the older format files.

You could give them the MDL, the older version should be able to read that.

Re: Automatizing optimization

I cannot think of a way of doing either of these. You could change the weights using some custom code, but that would require programming. For example, create the VPD file using something like VBA. Run the optimization using this VPD, manually stop it, and then write a new VPD before running again. ...
