Courses: SeaFEM

Compass latest FEM technology applied to Seakeeping Analyses

March 26th: Forty-five minutes webinar

SeaFEM is a suite of tools for the computational analysis of the effect of waves, wind and currents on naval and offshore structures. SeaFEM applications include ships, spar platforms, FPSO systems, semisubmersibles, TLPs, marine wind turbines and ocean energy harnessing devices.

SeaFEM includes a state-of-the-art radiation and diffraction solver, enabling direct time-domain analysis of the dynamic response of the structure. Furthermore, SeaFEM is integrated in the Tdyn environment, allowing seamless connection with the FEM structural solver RamSeries, to perform one-way and two-way implicit fluid-structure interaction analyses.

The webinar will introduce the latest features available in SeaFEM, including a cutting-edge time-domain second-order radiation-diffraction solver, a new algorithm for large rigid-body motion integration, a utility for air-gap calculation, an advanced dynamic cable FEM solver, new GUIs (Graphical user Interface) for mooring and slender elements definition, and a new linear frequency-domain solver based on the BEM (Boundary Element Method).

The different tools available in SeaFEM are fully integrated in a GUI for geometry and data definition, automatic mesh generation and visualizing the analysis results. SeaFEM GUI features a versatile tree-like interface for data managing, allowing an easy control of the whole process of entering the analysis data.

To facilitate the data definition process, SeaFEM provides tools to easily configure the type of the analysis to be carried out: seakeeping, maneuvering, towing or fluid-structure interaction). Furthermore, SeaFEM provides a variety of tools which allow having a perfect control over the process and assess its quality.

Who should attend?

This course is aimed at practicing engineers -mostly Naval Architects and Ocean Engineers- who wish to learn more about how to apply computational methods to seakeeping analysis in the most effective manner.

Tdyn CFD+HT and RamSeries users may also be quite interested in this webinar. It is a great opportunity for learning about this new advanced tool.
