The nonlinear dynamics of magnetic flux, moving in a vortex-free superconductor, is considered. It has been shown that the flux behavior strongly depends on both geometry and the boundary conditions. Stability analysis of flux front has been performed. The azimuthal instability caused by the thermal effect is predicted.
