摘要
This review article summarizes the basis and recent developments on the combined interface boundary condition (CIBC) method for the numerical simulation of fluid-structure interaction (FSI) problems. To represent the continual reciprocity between both media better, the CIBC method employs a Gauss-Seidel-like procedure to transform the traditional interface conditions into the velocity and traction corrections. A free parameter is adopted to control the effect of such a treatment on the fluid-structure interface. The thorough derivation of the CIBC method is presented, hence providing the theoretical basis of two improved formulations of the method. The relevant issues are deeply discussed for the numerical implementation. The CIBC method is subsequently introduced into various partitioned solution schemes. After describing all ingredients of our coupling strategies in detail, intensive FSI examples are tested to justify the feasibility, robustness and efficiency of the developed methodologies.
