Coupled BEM/hp-FEM Modelling of Moored Floaters
Paper i proceeding, 2018

A coupling between a dynamic mooring solver based on high-

order nite element techniques (MooDy) and a radiation-di
raction based

hydrodynamic solver (WEC-Sim) is presented. The high-order scheme

gives fast convergence resulting in high-resolution simulations at a lower

computational cost. The model is compared against a lumped mass moor-

ing code (MoorDyn) that has an existing coupling to WEC-Sim. The two

models are compared for a standard test case and the results are similar,

giving con dence in the new WEC-Sim-MooDy coupling. Finally, the

coupled model is validated using experimental data of a spread moored

cylinder with good agreement.
