Absorption Wave

This paper presents the validation of active and passive, made by a dissipation beach, numerical absorbing methods implemented in RANS-VOF FLUENT® code for modelling long time series of wave propagation interacting with coastal structures. Verification of both numerical techniques was performed in 2D – wave flume, and 3D – wave tank, this one using a multiple active absorption wave makers. The active absorption wave maker allows maintaining the incident wave generation and the mean water level along the time. Good results were obtained for 2D and 3D applications for active absorption wave maker at the generation boundary and both numerical beach and active absorption at the end of the flume/tank.

The authors have been developing a crack propagation analysis system that can model arbitrary shaped cracks in three-dimensional solids. In the system, automatic mesh generation program, parallel/large finite element program (ADVENTURE_Solid) and virtual crack closure-integral method (VCCM) for the quadratic tetrahedral finite element are used as its key-components. In this paper, the components in the crack propagation system are briefly described and some demonstration problems are presented for an illustrative purposes.
