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...

In order to fix any bugs, we need step by step instructions on how to make Vensim crash.

Can you upload the problem model and give step by step instructions on how to make vensim do this? Also let us know the exact version of vensim and the operating system you are running.

Did you re-publish the model after ticking the "Overwrite get...constants" in DSS?

Your profile says you are a PLE user. If you are a DSS user, please update your profile with valid licence information or email us and we can do it for you.

This is only available in Vensim Pro/DSS.

Can you email us directly regarding this please?

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.

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 ...

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.

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.

Your profile says you use PLE+, subscripts are not available in PLE+.

Yes, but subscripts are not available in PLE+.

Please upload your model to the forum if you have further queries.

Strange, I replied yesterday to say please email is directly and I'll assist (but the reply must not have been posted).

Please email with your licence details to vensim@vensim.com

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".

Let me know if this fixes it for you.

I've built the 64 bit version, just haven't had enough time to test it properly yet.

Not yet. I'm working on it though.

Can you email us direct and we'll take a look.

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.

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.

Ahh, sorry, a bit of confusion here.

If you open the help system, the tutorial is in there.

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. ...

We do have a Sable tutorial on our website, but I see there is no link to it on the page (I'll update that now).
