Data Exchange Method for solid body field Coupling Based on Compactly Supported Radial Based Function

This paper focuses on the data interpolation between non-matched thermal-electric solid body field meshes. A interpolation algorithm based on Compactly Supported Radial Based Function is proposed. The transfer matrix is derived and the calculation program used for data exchange between two non-matched meshes based on Compactly Supported Radial Based Function is developed. A group of examples of temperature interpolation between two non-matched meshes is tested, and the influence of different parameters on calculation time and precision is analyzed. The result shows that the algorithm in this paper is efficient and accurate for solid body field coupling interpolation especially for thermal-electric coupling interpolation.
