Hi Aniket,

Thank you for your reply.

I have looked this page.

In this page, 

Note: In a magnetostatic analysis, you can orient a polarization axis for a Linear or Nonlinear Hard material in either the positive or negative x direction with respect to a local or global coordinate system. Use the Material Polarization setting in the Details view for each body to establish this direction. The Material Polarization setting appears only if a hard material property is defined for the body. For a cylindrical coordinate system, a positive x polarization is in the positive radial direction, and a negative x polarization is in the negative radial direction.

 I set the model according to this message, however a negative x polarization did not become in the negative radial direction.
