• Radial basis function

This paper presents a simple strategy allowing to adapt well established isotropic BEM approach for the solution of coupled problems with anisotropic material parameters. The method which is illustrated on the case of a piezoelectric material is based on the partition of the primary fields into complementary and particular parts. The complementary fields solve the isotropic form of the partial differential equation while particular fields are obtained by a point collocation of the strong form equation. Using the local radial point interpolation method, the effectiveness and accuracy of approach is demonstrated on some examples allowing a comparison with literature results.
