Hi all,
I've tried running a simulation of Brazil and the US, but the graphs only seem to have connections and air travel with in a country, not between them. Is there a way to draw an edge from Brazil into the US? I'd like to start the infection in the northeast of Brazil and see if I can get it to travel into the US.

Thanks!

Download the USA/Mexico downloadable scenario for an example of how to do this
Go to the Graphs tab, expand it, and drag the air travel graphs with names ZZZ_1_ZZZ_0 into your model. The ZZZ nodes connect countries through international air travel (which uses a virtual node). The build in model does handle international travel.

Please also read the doc:
https://wiki.eclipse.org/Air_Travel_Model
https://wiki.eclipse.org/Triggering_interventions#Air_Transportation_Example

To make your own model please read the doc on 'Migration Edges' in the wiki.

Thanks! I was able to get a multi country model to run. FYI there seems to be some error with the built in (0,1,2,3) population model for the US. I was able to run the (0,1,2) model, but when I used the (0,1,2,3) nothing happened.

0,1,2,3 in the US was a contribution from U. Vermont that added level 3 regions for Vermont only. Thanks for the heads up - We'll check it out Smile
