| Outline of Final Research Achievements |
Regarding a numerical simulation method for the prediction of ship motions in damaged condition, which combines the estimation of hydrodynamic forces by a particle method for the damaged part and a potential theory for the intact part, an explicit MPS method which has good scalability was adopted and it was extended to a simulation code which can execute large-scale simulation on GPU clusters. This advancement makes it possible to use a sufficient number of fluid particles required for flooding analysis, so quantitative prediction of transient behavior of a Pure Car Carrier during flooding and of complicated flooding in the car compartment was realized. A significant progress was also made in the pre-processing that automatic generation of wall particles from CAD data was achieved. It was also confirmed that something new problems do not arise in the application to a large cruise ship.
