Data Exchange Method for Fluidstructure Interaction Based on Interpolation Algorithm Adopting Compactly Supported Radial Based Function

Abstract:

Based on principle of conservation of energy,a method adopting compactly supported radial basis function (CRBF) is proposed to perform fluidstructure interaction (FSI) analysis.The displacement transfer matrix H is deduced and a corresponding program by CRBF/FSI algorithm is developed.Example of displacement exchange with 3D interface is studied.The numerical solution by CRBF/FSI method is compared with analytical solution.The result shows that CRBF/FSI method is efficient and accurate.It is suitable for FSI data exchange with complicated interface and has a bright future in project application.

Key words:fluidstructure interaction; data exchange; compactly supported radial based function; energy conservation
