It is known that the critical current density of the second kind superconductor greatly depends on the shape of the pin and the positional relationship between the magnetic flux line and the pin. In this study, we numerically solve three dimensional time dependent Ginzburg - Landau (TDGL) equation to reconstruct the motion of the magnetic flux lines in the superconductor under the transverse magnetic field into the simulation space. The pinning effect of magnetic flux lines by columner pins was systematically investigated.
