The Camp Nou’s 3D digital Twin model from the IoTwins project has been developed in the supercomputer MareNostrum 4, which is property of the Barcelona Supercomputing Center (BSC). In addition, adaptations of the pilot project for testing purposes are already underway. During the Granada vs FC Barcelona match on 20 September, Monday, all the experimental trials conducted in the laboratory were taken at the stadium for the first time. This is a tool which will simulate and predict the behaviour of the attendees during a game, improving big facilities management. Besides, it will provide fans with comfort, safety, amongst other advances.
