Abstract
In fluid-structure interaction simulations using a partitioned approach, especially aeroelastic analysis, each physics component solves on its own mesh, and the interface between these meshes are in general non-matching. Force and displacement must be transferred from one mesh to another. Generally speaking, two classes of methods have been developed and applied in engineering: point wise interpolation and mapping method. For practical problems, point wise interpolation is not good enough in conversation and mapping method requires detailed meshes to describe surfaces of both fluid side and structure side. This paper presents a flexible, conservative and robust method which only requires surface mesh on fluid side. The merits of new method in terms of conversation properties were discussed. Also, the numerical results of practical problems are demonstrated in this paper.
