In order to simulate fire consequences in complex underground networks, we want to implement a coupling between a ID ventilation code and a CFD model or a zone model. The project consists in 3 main steps: the development of a ID ventilation code whose programming structure will support a coupling with another code, the definition of exchange of boundary conditions between the 2 codes and the validation of this exchange. In this paper we present our new ID code developed in this framework. A case study shows the global reaction of the flow to a fire and proves the interest of keeping into account the whole network instead limiting the calculation domain to a zone closed to the accident.
