Fast BEM Solution for 2-D Scattering Problems Using Quantized Tensor-Train Format
Abstract : It is common to accelerate the boundary element method (BEM) by compression techniques [fast multipole method (FMM), H-matrix/adaptive cross approximation (ACA)] that enable a more accurate solution or a solution in higher frequency. In this article, we present a compression method based on a transformation of the linear system into the tensor-train format by the quantization technique. The method is applied to a scattering problem on a canonical object with a regular mesh and improves the performance obtained from existing methods.
