Abstract
This paper presents an improved boundary element formulation for large-scale wave computations. A doubly bordered block diagonal coefficient matrix is directly derived and manipulated based on a separated kernel expansion, constant boundary elements, hierarchical block-element subdivision and substructure algorithm to the blocks, without resort to domain decomposition approach. Test calculations for acoustic waves offer promising results.
