Abstract:A study on the fluid-structure interaction using LSFEM is presented. To consider fluid-structure interaction, staggered scheme, which solves fluid and structure respectively by separate solvers in a predictor-corrector fashion, is used. To analyze fluid-structure interaction effectively, LSFEM is introduced in analyzing the fluid region. 2-D, incompressible and viscous fluid in the steady state is considered. The structure region is restricted in plane strain state including nonlinear behavior, and is analyzed by using commercial Galerkin FEM code ABAQUS. Also, a remeshing scheme for the fluid region using artificial spring elements is suggested. This solution procedure is applied to the flow around a slender structure problem and microvalve problem. The results are verified by comparing with the analytical solutions.
