Domain Decomposition in Structure-Acoustic Analysis

  • Göran Sandberg
Conference paper


Finite element analysis in acoustic and structure-acoustic engineering applications leads to large systems of equations. Today it is not unusual to have a demand for 500,000 degrees-of-freedom in an acoustic model. It is therefore of great interest to have simple procedures that will allow the engineer to divide the domain, thus splitting the analysis procedure into smaller problems. Also, changes in design often affect only part of a geometry; thus, only that part needs to be recalculated.
