Two kinds of the calculation technique are Investigated with 3D triangular SCM for the arrangement of the dielectric sphere with different resistivity under a uniform electric field. The calculation error of Method I is small outside the sphere, but considerably high Inside. On the other hand, the accuracy is much Improved even Inside the solid dielectric by Method II, which uses double layers of triangular charges on the dielectric boundary.
