Abstract
Reducing time-to-market, reducing development and production costs and
increasing acoustic comfort, means less physical prototyping and more
predictive modeling. However, predictive acoustic and vibro-acoustic models
using FEM and BEM methods have often had limited usefulness, partly due to
the long times taken to get the substantial amounts of results needed for
engineering design optimization.
In this paper, recently-developed technologies are presented which
accelerate acoustic solutions. An array of approaches is presented, using finite,
infinite and boundary element methods, which are based on re-usable Modal
Acoustic Transfer Vectors, Pad6 methods for rapid frequency-sweep solutions,
domain decomposition, finite element iterative solvers and multi-processor
'netsolvers'. These technologies make for timely and effective acoustic
predictions, whi
