The maneuver behavior is analyzed via maneuvering coefficients, which are gained by free running maneuvers based on computational fluid dynamics (CFD) simulations. The numerical study is conducted on the generic submarine model BB2 in model scale with STAR-CCM+. Overset mesh technology is used to simulate the body in six degrees of freedom. The simulation is controlled via a JAVA program. Appropriate proportional-integral-derivative (PID) gains are used to set and control the maneuvers. This study investigates the obtainment of certain coefficients through maneuvers in one plane.en1053-538120214395402BB2Free running CFDOverset meshPID controlRigid body simulationSTAR-CCM+UUVJournal Article10.17736/ijope.2021.jc830Other
