Comparison of Finite-Element and Finite-Difference Schemes. Part II：Two-Dimensional Gravity Wave Motion
Finite-Element Finite-Difference Schemes Two-Dimensional Gravity Wave Motion
2009/2/23
Irregular grid finite-difference techniques lead to equations similar to those obtained using finite-element techniques. The simpler finite-difference equations offer the advantage of greater computat...
Comparison of Finite-Element and Finite-Difference Schemes. Part I：One-Dimensional Gravity Wave Motion
Finite-Element One-Dimensional Gravity Wave Motion Finite-Difference Schemes
2009/2/23
The finite-element scheme requires more computational expense because it is time-implicit and because it requires a smaller time step than the finite-difference scheme. Simulations of normal mode osci...
Normal Modes of the World Ocean. Part I. Design of a Finite-Element Barotropic Model
Normal Modes World Ocean Finite-Element Barotropic Model
2009/2/23
The linearized primitive equations for a barotropic world ocean are discretized by means of first-order, piecewise-linear finite elements. Surface elevation and Stokes/Helmholtz velocity potentials ar...
Interaction of Tsunamis with the Hawaiian Islands Calculated by a Finite-Element Numerical Model
Tsunamis Hawaiian Islands Finite-Element Numerical Model
2009/2/23
A finite-element numerical model is used to determine the interaction of tsunamis with the Hawaiian Islands. The model employs a finite-element grid which telescopes from a large cell size in the deep...
A Finite-Element Solution Procedure for the Interpolation of Current Data in Complex Regions
Finite-Element Solution Complex Regions Current Data
2009/2/19
A finite-element solution technique is introduced to develop current patterns subject to geostrophic and Ekman dynamics for an irregular continental shelf region. The interpolation bases set of functi...
Numerical Simulation of the 29 November 1975 Island of Hawaii Tsunami by the Finite-Element Method
Numerical Simulation Finite-Element Method Hawaii Tsunami
2009/2/13
The finite-element method is applied to study the transient response of a locally generated tsunami. The model time-steps the linearized shallow-water wave equation over a variable mesh of triangular ...
