Who Should Attend

This course is intended for any engineer involved or interested in CFD modeling of marine problems. Prior experience with a CFD tool, preferably STAR-CCM+, is strongly recommended but is not required.

Course Description

The aim of this course is to teach the techniques needed to conduct accurate and efficient marine simulations using computational fluid dynamics. The course is structured as a combination of lectures, demonstrations and workshops (tutorials). Best practices for meshing and analysis of stationary and multi-degree-of-freedom (DOF) free-surface applications are emphasized and demonstrated. The course begins with a review of the fundamental principles of marine engineering before moving onto discussions of typical marine geometries and demonstrating in detail, the import, preparation and meshing of those geometries for computational analysis. Attendees will construct a model of a typical ship geometry and perform a free-surface resistance analysis. Subsequent lectures, demonstrations and workshops build on this example, and include calculation of vessel sinkage & trim, modeling of waves and associated response (seakeeping), and modeling and analysis of propellers.
