A Multi-Resolution MPS/FEM Coupling Method for Three-Dimensional Fluid–Structure Interaction Analysis

This work aims to propose an efficient MPS/FEM coupling method for the simulation of fluid–structure interaction (FSI), where MPS and FEM are respectively employed account fluid flows structural deformation. The main idea our is develop a multi-scale multi-resolution simulations in context coupling. In developed method, domain discretized into particles different resolutions before calculation, close interest will be high resolution, while rest low resolution. A large particle interacting with small divided several virtually, weight functions redefined maintain stability. bucket-sort-based algorithm fast search neighboring particles. capacity newly proposed ghost cell boundary model further enhanced, so as accurately treat wall problems resolutions. On this basis, coupled FSI simulations. Finally, numerical examples conducted demonstrate accuracy efficiency development method.
