Fast multipole boundary element method
WebAug 4, 2024 · Approach: The recently developed charge-based boundary element fast multipole method (BEM-FMM) is employed as an alternative to the 1st order finite element method (FEM) most commonly used today. The BEM-FMM approach provides high accuracy and unconstrained numerical field resolution close to and across cortical … WebApplying the Boundary Element Method to such problems is not straightforward. However, the Boundary-Domain Integral Method (BDIM) can be used, which requires to solve beside the boundary integrals as well a domain integral due to the inhomogeneity. ... To reduce the quadratic complexity in BEM, approximation methods like the fast multipole ...
