针对热－电场耦合仿真计算中非匹配网格之间的数据插值问题，提出了一种基于紧支径向基函数点插值的数据传递方法。推导了数据传递矩阵，根据所提出的数据传递方法编制了非匹配网格之间数据传递计算程序，以若干组非匹配网格之间的温度插值为例进行了验证，并分析了不同参数对计算时间及精度的影响，结果表明，算法效率较高，计算误差较小，适用于以热－电场耦合为代表的固体域耦合非匹配网格间的数据传递计算。

According to the data interpolation problems of non-matched meshes in the simulation calculation of thermal-electric solid body field,a interpolation algorithm based on compactly supported radial basis function was proposed.The transfer matrix was derived and the calculation program used for data exchange between two non-matched meshes based on compactly supported radial basis function was developed.An example of several groups of temperature interpolation between two non-matched meshes was verified,and the influence of different parameters on calculation time and precision was analyzed.The result shows that the algorithm is efficient and accurate for data exchange calculation of solid body field coupling non-matched meshes,especially for thermal-electric coupling interpolation.
