A volume-conserving ALE continuous Galerkin method with residual-based Dirichlet--Neumann fluxes for nonlinear free-surface waves
We develop an arbitrary Lagrangian--Eulerian continuous Galerkin finite element method for two-dimensional fully nonlinear free-surface potential flow. An isoparametric finite element method computes the interior potential on the current fluid domain, while a residual-based Dirichlet--Neumann flux drives the surface ev...
