This paper deals with the aim of coupling multigrid generation of boundary-fitted grids with an effective domain decomposition technique. We present multiblock grid generation algorithms for efficient solutions of domain discretization problems. We propose the generation of structured grids by...

The transport of classical waves in strongly scattering media is investigated using ultrasonic techniques, allowing us to measure both the ballistic and scattered components of the wave field. We find that the ballistic propagation is dramatically slowed down by scattering resonances, although...

Scattering phenomena in inhomogeneous media are strongly linked to the volumetric fraction and the composition of the particles. For high concentrations, dependent-scattering effects appear, giving rise to interactions which are different from those described by independent multiple scattering...

The purpose of this work is to find the time-dependent distributions of directions and positions of a particle that undergoes multiple elastic scattering. The angular cross section is given and the scatterers are randomly placed. The distribution of directions is found. As for the second...
