A coupled BEM and FEM for the interior transmission problem in acoustics
نویسندگان
چکیده
The interior transmission problem (ITP) is a boundary value problem arising in inverse scattering theory which has important applications in qualitative methods. In this paper, we propose a coupled boundary element and finite element method for the ITP. The coupling procedure is realized by applying the direct boundary integral equation method to define the so-called Dirichlet-to-Neumann (DtN) mappings. We show the existence of the solution to the ITP for anisotropic medium. Numerical examples are provided to illustrate the practicability of the coupling procedure.

متن کاملThe Acoustic Diffusion Model for Single and Coupled Interior Volumes Using the Boundary Element Method
Recently, a new model for the propagation of sound in interior volumes known as the acoustic diffusion model has been explored as an alternative method for acoustic predictions and analysis. The model uses statistical methods standard in high frequency room acoustics to compute a spatial distribution of acoustic energy over time as a diffusion process. For volumes coupled through a structural p...

Given any structure, we seek to find the solution of mechanical problem as precisely and efficiently as possible.

Moreover, in BEM the modeling of infinite means is performed naturally, without the use of appro...
متن کاملA coupled finite element-boundary element method for modeling Diffusion equation in 3D multi-modality optical imaging
Three dimensional image reconstruction for multi-modality optical spectroscopy systems needs computationally efficient forward solvers with minimum meshing complexity, while allowing the flexibility to apply spatial constraints. Existing models based on the finite element method (FEM) require full 3D volume meshing to incorporate constraints related to anatomical structure via techniques such a...
