ABSTRACT:
Techniques for creating an acoustic model from a finite element mode include strategically partitioning elements of the finite element model into sets, forming composite centroids from the partitioned elements and then calculating the spatial distances between the composite centroids so that an acoustic model can be created using a tiny portion of the computational power otherwise required. By further constraining the composite model to conform to an M-by-N array, object-oriented code can be used.
