Abstract
When the force to be calculated is very small, it is not easy to calculate the force with high accuracy by the nodal force method because that occur the calculation error due to the discretization error of the finite element analysis(FEA). In this paper, we investigate a technique in order to calculate the force with high accuracy through the magnetic levitation force and torque analysis of a diamagnetic material. The levitation force can be calculated with high accuracy using the extreme fine mesh in domain integration of the nodal force. The very small torque can be calculated with high accuracy by symmetrizing the mesh in the domain of integration of the nodal force.
