Abstract
The computation of free surface flows is challenging since waves are highly nonlinear and commonly present merging, frag mentation and cusps, leading to the use of interface capturing ALE approaches. Turbulence is also important on several offshore applications. In this work we report recent advances of EdgeCFD to simulate these problems. EdgeCFD is a fully implicit 3D incompressible stabilized parallel edge-based finite element flow solver associated to the Volume-of-Fluid (VoF) method. The VoF marking function is also solved by a fully implicit parallel edge-based finite element formulation. Turbulence in EdgeCFD is treated within the Large Eddy Simulation (LES) framework. The performance and accuracy of EdgeCFD is tested in the simulation waves and in the interaction between waves and a semisubmersible structure. We also access the performance of several LES models on the simulation of the flow around a cylinder at Reynolds 3,900.
