Field notes
The demo explains flow direction through the imbalance between the teams’ output, then ties over-limit pushing to heat buildup and a temporary trip. The page says its four-step offline tutorial uses the same simulation code as the multiplayer game. Maps vary link characteristics: the Baltic map has lower losses, while the Pacific map represents a much longer link with larger losses.
