Initial Value Problem Formulation of 3-D Time Domain Boundary Element Method

Application of Boundary Element Method to 3 D Submerged Structures With Open Ends (RESEARCH NOTE)

This paper presents a three dimensional application of direct Boundary-Element Method (BEM) for computing interaction of sinusoidal waves with a large submerged open bottom structure near the floor with finite depth. The wave diffraction problem is formulated within the framework of linearized potential theory and solved numerically with direct BEM. A computer program based on BEM is developed ...

Wake Field Analysis by Time Domain Bem with Initial Value Problem Formulation

This paper presents a new formulation of the Time Domain Boundary Element Method (TDBEM), an initial value problem formulation, for particle accelerator wake fields analysis. Conventional formulation of the TDBEM had some difficulties in practical uses, instabilities caused by interior resonance, larger memory requirement, initial value setting, etc. To solve these problems, the initial value p...

Global Existence and Uniqueness of the Non - stationary 3 D - Navier - Stokes Initial - boundary Value Problem

We present a global unique weak   2 / 1 H solution of the generalized 3D Navier-Stokes initial value problem (for all 2 / 1  H v ) 0 ) , ( ) , ( ) , ( 2 / 1 2 / 1 2 / 1       v Bu v Au v u 2 / 1 0 2 / 1 ) , ( ) ), 0 ( (    v u v u . The global boundedness is a consequence of the Sobolevskii -estimate of the non-linear term ([SoP]) enabling the generalized energy inequality 2 1 2 /...

Time Domain Simulation of Steady Ship Wave Problem by a Higher-Order Boundary Element Method

A 3-D time-domain numerical wave tank using a higher-order boundary element method is newly developed in the framework of linear potential theory, and ship waves generated by the standard Wigley model advancing at constant forward speed in otherwise calm water and the resultant steady wave resistance are computed as verification of the computer code developed. A rectangular computational domain...
