• A computer simulation of magnetic domain wall motion was performed in order to study the dynamic bubble-collapse process under a wide range of drive fields. An unichiral bubble with a circular symmetry in a garnet film was assumed for simplifying the computation. The instantaneous bubble radius, horizontal Bloch line propagation, and wall overshoot effect were studied as well as the time-averaged wall velocity during the collapsing process. The time-averaged velocity of the bubble wall was compared with the results of the simulated velocity of a plane wall and the velocity measured in the dynamic bubble collapse experiment. There was a fair agreement among these velocities, but a slight difference in saturation velocity between bubble wall and plane wall was found. It originated from a difference in the surface stray in-plane field for these two geometries.
