Can you post the venapp you are using? It's impossible to really advise you unless we can see what commands are being executed.

Re: Lookup function
Are you using PLE? If yes, just draw an arrow from your lookup to the variable where you need to use it.

Re: Lookup function
If you read through
http://www.vensim.com/documentation/ind ... ?usr08.htm
It will show you how to create a lookup (and how to use it).

Re: simple question regarding error
Is there a Stella forum where you can ask for help? I know there are one or two who use this forum who are familiar with Stella, but you would most likely get a much faster answer elsewhere.

Re: publishing model via code
You can only publish a model for use with the Vensim DLL if you have Vensim DSS. The Vensim DLL is only licenced for use with Vensim DSS (the DLL only comes with DSS). So if you only have PLE, there is no way you can publish a model for use with the DLL as you are not licensed to do so. These are li...

Re: Vensim PLE- giving priority
Yes, just replicate the structure I have put in. Or allocate based on a proportional demand basis.Is there a way to further allocate the flows based on priority between these 3 flows?

No. This is by design, you would not need Vensim if you could publish a model via some other means.

Click Model->Simulate and then "Advanced". Here you can enter your data files.

Re: Multiple Rate Valve in one pipe
It's up to you. Give it a try and see if you get the results that you need from the model.I want to share different percentage to different variable from one variable through pipe. will it be appropriate to use two valve or just take a link from same arrow?

One other thing to remember. Your profile indicates that you are a PLE user, subscripts are not possible with PLE.

Re: Slow Response Using SubScript Grid Command
A screenshot doesn't help at all. I need to be able to re-create the problem to have any chance of giving some advice.
The screen itself does not contain any data, if you can just email that to me I can have a go.

Re: GET DIRECT SUBSCRIPT Problem
The only thing you can do here is move the constant values into a CIN file (which is good practice anyway) and then just add the new constant values.

At my company we continously re-use a standard model, and we would like to reduce the effort required to do this, to set up a new instance of the model. For that, being able to add new elements to a family of subscripts at the touch of a button would be great - especially if that could also be done...

Re: From steady-state to dynamic model
When you run a model, it generates a VDF file. This VDF file can be used in other simulations.
