Boundary and coupled boundary–finite element methods for transient wave–structure interaction

Finite Element and Boundary Element Methods for Transient Acoustic Problems

The paper focuses on the numerical treatment of transient acoustic problems using finite element (FE) and boundary element (BE) methods. The FE method relies on a pressure formulation and the use of an implicit integration schemes for solving the related second-order differential system. The procedure is shown on cavity (interior) problems but can be extended to exterior problems using the DtN ...

Coupled Boundary and Finite Element Tearing and Interconnecting Methods

We have recently introduced the Boundary Element Tearing and Interconnecting (BETI) methods as boundary element counterparts of the wellestablished Finite Element Tearing and Interconnecting (FETI) methods. Since Finite Element Methods (FEM) and Boundary Element Methods (BEM) have certain complementary properties, it is sometimes very useful to couple these discretization techniques and to bene...

Boundary Element Methods for Inductive Hardening

This study deals with the simulation of inductive hardening of conducting workpieces made of steel. The aim is to calculate the propagation of heat in the workpiece. Based on this knowledge, the hardened zone can be predicted with sufficient precision. Since the simulation is to be applied in industry, workpieces and inductors are supposed to have a complex three dimensional shape. The electrom...
