APPLICABILITY OF COMBINED BEM-VOF METHOD TO RANDOM WAVE COMPUTATIONS

Seismic Wave Scattering Through a Compressed Hybrid BEM/FEM Method

Approximate numerical techniques, for the solution of the elastic wave scattering problem over semi-infinite domains are reviewed. The approximations involve the representation of the half-space by a boundary condition described in terms of 2D boundary element discretizations. The classical BEM matrices are initially re-written into the form of a dense dynamic stiffness matrix and later approxi...

A Combined BEM/FEM Method for IC Substrate Modeling

Simulation of Wave Impact on Inclined Deck Based on VOF Method

The increasing importance of the sustainability challenge in ocean engineering has led to the development of floating structure of various configurations. In this study, a numerical wave tank based on the Navier-Stokes equations has been established. The turbulence model, namely standard k-ε is incorporated to the numerical tank to broaden applicability of simulation. The VOF method has been wi...

Analysis of a FEM/BEM coupling method for transonic flow computations

A sensitive issue in numerical calculations for exterior flow problems, e.g. around airfoils, is the treatment of the far field boundary conditions on a computational domain which is bounded. In this paper we investigate this problem for two–dimensional transonic potential flows with subsonic far field flow around airfoil profiles. We take the artificial far field boundary in the subsonic flow ...

Applicability of Program Comprehension to Sparse Matrix Computations

Space{eecient data structures for sparse matrices typically yield programs in which not all data dependencies can be determined at compile time. Automatic pa-rallelization of such codes is usually done at run time, e.g. by applying the inspector{ executor technique, incurring tremendous overhead. | Program comprehension techniques have been shown to improve automatic parallelization of dense ma...
