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.

Yes, we are aware. There are much bigger problems with the Mac at the moment due to the latest Xcode/SDK.

Re: Close Excel when exiting Vensim (if opened) won't stay active
Thank you.
This setting is also under the "Excel" settings window, so I'll remove it from the "General" section in the next Vensim release.

Re: Unable to open Vensim
If you've used Vensim before, try deleting or renaming the .venple file in your home folder (it's hidden).
This will mean Vensim starts with default settings, maybe you had the old GUI running before?

Re: unit conversion
Yes. Create an unchangeable constant called "kg per lb", give it the correct units (kg/lb) and value (0.453592). Then you can use it to convert any kg or lb measurements in your model.

Re: Multi-input Lookup
I'm struggling to follow at what you are doing here. Subscripts are usually used to turn one variable into an array. So you could have a variable called "sales" and this could be subscripted by "region". I've had a go at building something simple that I think might be what you ar...

Re: impossible to switch back to the old gui a model built with the new guide
Do you have a timeline for retiring Venapps and introducing web publishing? We have a client that needs a flight simulator in Q2 2024 (preferably April vs June) and web would be a much better solution. You can already publish to the web via Vensim DSS. This gives you a model that will happily run i...

Re: where is the sim set up from the old GUI in the new one?
I'm currently travelling so don't have a computer in front of me. It's to the left of where you enter the run name. It should also have a tool tip, so hold the mouse over each button until you find it.
