Kurzfassung
The boundary-element subregion-by-subregion (BE SBS) algorithm, developed in previous works, is employed to construct global block-diagonal preconditioners for BEM systems of equations. As the BE matrices for each BE subregion are independently assembled and stored, the block-diagonal-based preconditioners for the corresponding BE models are immediately constructed. A Krylov solver is embedded in the SBS algorithm, and this work, particularly, the Bi-CG solver is considered. The micromechanical analysis of large-order 3D representative volume elements (RVEs) of carbon-nanotube (CNT) composites are carried out to show the performance of the preconditioned iterative solver.
