Purpose - To develop a technique to couple the lattice Boltzmann method (LBM) and the finite element method (FEM) to solve fluid-structure interaction (FSI) problems.
Design/methodology/approach - The FEM was applied to structural analysis while the LBM was applied to fluid flow analysis. The two techniques were coupled in a staggered manner through interface boundary conditions.
Findings - In order to demonstrate the developed coupling technique, various FSI examples were analyzed and presented. The coupling technique was useful to solve FSI problems.
Originality/value - To the best knowledge of the author, there have been few efforts to couple the two techniques to solve the fluid and flexible structure interaction problems.
