Moving mesh method with local time step refinement for blow-up problems

Abstract In this paper, the dynamical moving mesh method is merged with the local time stepping technique and the new method is applied for blow-up problems. It has some benefit in approximating an accurate blow-up time by starting at any positive initial time ( t 0  > 0). Our numerical experiment shows that without applying the local time stepping method, wrong blow-up time will be obtained, if the equation integrates from t 0  > 0.
