FRyDoM-ce: Flexible and Rigid body Dynamics modeling for Marine operations (Community Edition)

FRyDoM-ce is an open source framework for the simulation of complex systems involved in marine operations for Marine Renewables. FRyDoM is a physics-based modeling and simulation framework dedicated to complex marine platforms, structures, systems and operations. Built on a powerful multipurpose multibody dynamics numerical core, its object oriented modular architecture is designed to be embedded in a large range of application; from embedded systems up to Virtual Reality Solutions.

Implemented in modern C++, FRyDoM is released under open source GPLv3 (see LICENCE file) in order to provide a high-end framework to the marine community.

FRyDoM-ce (community edition) is the property of Ecole Centrale de Nantes and is maintained by DICE-Engineering company. D-ICE Engineering is currently developing training sessions programs that will help you to master FRyDoM framework. Please contact FRyDoM training for more details.

This work was carried out within the framework of the WEAMEC, West Atlantic Marine Energy Community, and with funding from the Pays de la Loire Region.
