Time Domain Boundary Element Method for Room Acoustics

seismic waves scattering in three-dimensional homogeneous media using time-domain boundary element method

it is well established that the seismic ground response of surface topographies may differ from those of free field motion during earthquakes. complex nature of seismic wave scattering by topographical structures can only be solved accurately and economically using advanced numerical methods under realistic conditions. among the numerical methods, the boundary element is a powerful numerical te...

General time-dependent analysis with the frequency-domain hybrid boundary element method

The paper presents an attempt to consolidate a formulation for the general analysis of the dynamic response of elastic systems. Based on the mode-superposition method, a set of coupled, higher-order differential equations of motion is transformed into a set of uncoupled second order differential equations, which may be integrated by means of standard procedures. The first motivation for these t...

Computation of Sound Propagation by Boundary Element Method

A Domain Decomposition Method Combining a Boundary Element Method with a Meshless Local Petrov-Galerkin Method

A non-overlapping domain decomposition algorithm combining boundary element method with meshless local Petrov-Galerkin method is presented for solving the boundary value problem with discontinuous coefficient in this paper. The static relaxation parameter is employed to speed up the convergence rate. The convergence range and the optimal value of static relaxation parameter are studied, but the...
