An algorithm for generating and connecting 3-D nonconforming mesh with Finite Volume Method FVM is developed. The accuracy and computational performance using the nonconforming mesh technique are compared with those using the conventional conforming mesh. The algorithm is applied to solve a 3-D magnetostatic workshop problem proposed by IEEJ. It is shown that the memory requirements and CPU time using the nonconforming mesh can be decreased to about 1/2 of those using the conforming one. Moreover, the accuracy of the magnetic flux density is significantly improved.
