Discontinuous Galerkin Method for Linear Free-Surface Gravity Waves
نویسندگان
چکیده
• Weak formulation: – Involves a typical primal DG formulation for the Laplace equation (see Arnold et al. (2002)). – Adopt the numerical flux proposed by Brezzi et al. (1999). – Second order accurate time discretization is used for the time derivative in the free surface boundary condition (Van der Vegt and Tomar (2005)). • Finite element discretization results in a symmetric and positive definite linear system. This property gives stability to the present method.

A Runge-Kutta discontinuous Galerkin method for linear free-surface gravity waves using high order velocity recovery
We present a higher order accurate discontinuous Galerkin finite element method for the simulation of linear free-surface gravity waves. The method uses the classical Runge-Kutta method for the time discretization of the free-surface equations and the discontinuous Galerkin method for the space discretization. In order to circumvent numerical instabilities arising from an asymmetric mesh a stab...
متن کاملSpace-Time Discontinuous Galerkin Method for Large Amplitude Nonlinear Water Waves
A space-time discontinuous Galerkin (DG) finite element method for nonlinear water waves in an inviscid and incompressible fluid is presented. The space-time DG method results in a conservative numerical discretization on time dependent deforming meshes which follow the free surface evolution. The dispersion and dissipation errors of the scheme are investigated and the algorithm is demonstrated...

A new variational (dis)continuous Galerkin finite element method is presented for linear free surface gravity water wave equations. In this method, the space-time finite element discretization is based on a discrete variational formulation analogous to a version of Luke’s variational principle. The finite element discretization results into a linear algebraic system of equations with a symmetri...

Accurate simulation of Rayleigh waves is of critical importance in a variety of geophysical applications, such as exploration geophysics, geotechnical characterization, and earthquake-related damage assessment. Based on recent works on staggered discontinuous Galerkin methods, we propose for the simulation of Rayleigh waves a new method which enjoys energy conservation and extremely low grid di...
متن کاملElement free Galerkin method for crack analysis of orthotropic plates
A new approach for analyzing cracked problems in 2D orthotropic materials using the well-known element free Galerkin method and orthotropic enrichment functions is proposed. The element free Galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. In this study, element free Galerkin is extrinsically enriched by the recently developed crack-tip orthot...
