... ABSTRACT The potential numerical wave flume is applied in this study to estimate the forces and the moment on a submerged plate in the combined wave-current flow by solving the Laplacian equation based on the higher order boundary element method (HOBEM). The free surface motion is tracked...

... around the pusher-barge system, a higher-order boundary element method (HOBEM) with wave green function in frequency domain is implemented. For the pusher-barge system, six degrees-of- freedom (6DOF) motion are evaluated and discussed for three different heading angles in deep water conditions...

... ABSTRACT: In this paper, the focused wave and current interaction with a moored JIP Spar platform are investigated using a time-domain higher order boundary element method (THOBEM). Embodied by a linear superposition of finite cosine waves, the focused wave can be efficiently simulated through...

... element method (BEM) is used to solve the governing equation and boundary conditions of the fluid domain. The finite element method (FEM) is employed for solving beam equation of motion. The study investigates the effects of shear deformation and rotary inertia, relative beam stiffnesses, rotational...

... ABSTRACT: A time-domain higher-order boundary element method (HOBEM) is used to simulate the linear and fully nonlinear waves in a threedimensional numerical wave tank (NWT). In order to eliminate reflective waves at the incident boundary and output boundaries, damping layer combined...

... in which the potential energy of stretching and virtual work done by other forces are included The stationary condition of the functional and one of two equilibrium equations are used to solve the problem. Application of the finite element method yields a system of nonlinear equations, which is solved...

... ABSTRACT The discrete element method has been applied successfully to the elastic analysis of a wide variety of highly non-linear problems in structures under conditions of gross deformations. For certain types of frame it has been found possible to program this method of second-order analysis and account...

... IS commonly used to evaluate the wave forces on large offshore structures. In general, there are two classes of numerical solution techmques for the wave diffraction and radiatIon problems. They are the Integral equatIon method and the finIte element method. The mtegral equa- non formulations are more...
