The boundary element method (BEM) has become established as a powerful alternative to finite element modeling for a variety of automotive engineering solutions. In particular, it has been effective in the static analysis of powertrain components and also for the acoustic analysis of both the passenger compartment and the air-space surrounding a vehicle. While the technique offers a substantial improvement in case of use and modeling times for many problems, especially those described above, and also produces highly accurate solutions, the only drawback of the BEM has been its somewhat more limited range of analysis types. This paper describes how the Dual Reciprocity BEM technique has been applied in a commercial BEM package to offer a solution for dynamic analysis.
