Ventana software support forum

Hello,
I'm looking at some example models trying to understand if the model structure changes with and without using sub-models. However, neither of the example models work and their structures are exactly the same. Could I have two working models for comparison? I'm attaching non-working examples here.

Another question I have is whether Vensim provides a graphical presentation of how different sub-models are linked via which variables. I used other software and this can be done easily but the tutorial on Vensim is somewhat limited. Any help is highly appreciated. Thank you!

market_model_original runs for me. What errors are you getting?

market_model should have some additional models with it. Do you have them in the same folder?

There isn't yet an automated graphical representation, but it's on our todo list.

I ran the market_model in the same folder of Vensim sample model where "advertising" and "products" are stored.
The errors I got:
1. The variable "Products" and perhaps others require a data file to be specified.
2. Unable to correctly load in exogenous values - aborting.

Am I suppose to make the connections between the sub-models and the main model? I was under the assumption that the work has been done for me.
Thank you!

Yes, you have to make the connections by yourself between the main model and the submodels and it will then work. JJ

I get the same error message. How should I make this connection?

You need Vensim DSS/Pro for sub-models.
