This paper presents an overview of a CFD Opensource tool and its applications in industry and academia. A study case of a cruise ship flooding simulation is presented to show its capacity. To ensure the reliability of the results, a grid convergence analysis was performed and compared with benchmark data provided by FLARE, a European consortium that provided open data on flooding benchmarks. Additionally,  general arrangement layout modifications were tested. The main corridor width was changed, and water elevation probes were placed in different rooms to evaluate the change in the corridor width. Results showed that when the corridor width increases, the time to flood reduces for the rooms far from the breach. This behavior was opposed to the room near the breach, requiring a longer time to fill the room as the corridor width increased. The study case showed that studies with small variations could be important for ship design purposes, for instance, and doing that in experimental facilities is expensive, showing the necessity of good numerical free and open-source tools, such as OpenFOAM.
