Tdyn SeaFEM, software for the analysis of the effect of
waves, wind and currents
Tdyn SeaFEM features include:
Tdyn SeaFEM features unique capabilities for global performance analysis of moored and/or connected systems subject to random sea states. It includes built-in multi-segment quasi-static elastic-catenary and FEM dynamic cable models for the most realistic analyses of mooring systems.
Tdyn SeaFEM’s multi-body functionality offers a rich range of connections between bodies, including rotation, line and plane constraints, rotation and translation links, and rigid body, ball, revolute, cylindrical and prismatic joints.
Tdyn SeaFEM allows seamless communication of the hydrodynamic forces to the structure.
Furthermore, a unique hydroelasticity analysis GUI allows performing structure-waves interaction studies for strength assessment of the design. This capability is powered by the cutting-edge FEM technology available in Tdyn’s structural solver, Tdyn RamSeries
Thanks to its advanced pre-processing capabilities, based on Tdyn suite’s GUI, SeaFEM can easily model complex geometric structures with a best-in-class model preparation time.
Additionally, Tdyn SeaFEM can import standard CAD files, and has direct connection with some popular CAD packages.
Tdyn SeaFEM offers a wealth of intuitive visualization capabilities, delivering a flexible way for analyzing the results, and driving faster decisions with confidence.
