Efficient Multikernel Hierarchical Compression for Boundary Element Matrices
Résumé
We present a new scheme that allows
for the compression of operators of the combined field
integral equation in the low-frequency regime using a
hierarchical decomposition that leverages a unified
pseudoskeleton approximation of both the single- and
the double-layer Green’s function at the quadrature points.
Compared with a standard adaptive cross approximation,
the numerical results show a reduced memory consumption
without sacrificing computational run time.
