In the simulation, the discretization region is in the cross section normal to the film plane. It is clarified that the wall structure is strongly related to pinning characteristics. Depinning fields of the wall having a flux-closure asymmetric vortex (C-shaped wall) are different in the wall movement directions due to the asymmetric wall structure. On the other hand, depinning fields of the wall with two vortices (S-shaped wall) which have a symmetric structure do not depend on the wall movement direction. Depinning fields for the S-shaped wall are different from both depinning fields for the C-shaped wall.
