Ship design optimization framework

Abstract

This study intends to develop a Computational Fluid Dynamics space exploration frame-work, which creates a bridge between NAPA software and OpenFOAM 9 simulation soft-ware. With the use of Free Form Deformation function implemented in NAPA, iterations of KCS hull were automatically generated by changing the length of the bulb. The newly created versions of the model were further analyzed with numerical investigations to de-termine the ship resistance simulation using RANS equations. The optimization process and the data transfer between the two software packages is monitored by the Dakota op-timization software.
