An ℋ-matrix based direct solver for the boundary element method in 3D elastodynamics

Autor: Luca Desiderio

Publikováno v: AIP Conference Proceedings.

In this work we present a fast direct solver for 3D elastodynamic problems in frequency-domain. We use the Boundary Element Method as discretization technique, in association with the hierarchical matrix technique for the fast solution of the resulti

The solution of the elastodynamic equations using boundary element methods(BEMs) gives rise to fully-populated matrix equations. Earlier investigations on the Helmholtzand Maxwell equations have established that the Fast Multipole (FM) method reduces
