Re: Vensim training
For the model I am running multiple scenarios with different parameter values. I am doing this manually which takes up a lot of time and is sensitive to errors. I thought the use of scripts was only available for the Pro version of Vensim, but looking at your answer I think it is also possible in D...

Re: Can the Vensim PLE version achieve seasonal forecasting?
Start by adding units to your model. I would not bother simulating or doing anything else until your model passes this basic quality check. I can immediately see a problem (you've got a variable called month).

Re: Vensim training
For the system dynamics model that I am working on, I am using the Vensim Professional license. However, I would like to start with the automatisation of runs, parameter tuning etc. Is it true that this is not possible without the Vensim DSS license? Can you explain what you mean by this? If you me...

What version of Vensim are you using? And new or old GUI?
Can you upload a sample model, as this should not happen.

Re: Units tips or laws
Units should be (and are) easy. If you have a level and you have cars in it, the unit should be "cars". If you have people in a population variable, the unit should be "people". If you have a rate such as birth rate, it should be people/year (or per month etc). - For auxiliary va...

Re: Utilizing Ventana Systems Tools for enhancing data breach protection strategies ?
I've got no doubt that you can use both Vensim and Ventity to help. What you are describing sounds like a major project, it's not something that any of us could give you a few pointers to get you going.

Do you really need to export the whole file? You can use a savelist to export just the data you need.

In theory there is no maximum file size. It's going to take a lot of time though to export something that size.

Re: Cannot run Vensim after install
From the wiki page,
You should definitely move to Windows 10.Mainstream support for the Embedded Standard edition of Windows 8 ended on July 10, 2018, and extended support ended on July 11, 2023. As of August 2023, 0.35% of PCs are running Windows 8.

Re: Cannot run Vensim after install
I don't think Windows 8 is supported any more so it's unlikely Vensim will run on it.
You can try an older version, or even better, update to a supported operating system.

Re: Export as SVG not workingn correctly for new sketch style
I think that's more or less the best we can do with the newer sketch style.
I'll see if we can adjust things to line up the pipes. But the curves and drop shadows don't seem to be drawn at all.

Re: Unable to converge simultaneous loop
Have you been through any of the Vensim tutorials? I would start with the PLE tutorial at the following page,
http://www.public.asu.edu/~kirkwood/sysdyn/SDRes.htm
This will get you to the point where you can build a basic model. Once you've done this, I'd start again.

Re: How to publish a model using DLLs?
Sorry, I misunderstood your first mesage.
No, you cannot do this via the DLL. The DLL will only open published models, so there is no way to get the MDL file into the DLL in order to publish it. You need to run these commands in Vensim via a command script.

Re: Unable to converge simultaneous loop
You'll need to upload your model for us to be able to help.
It's rare that you even need to use this function, my guess is you have some sort of formulation problem.
