Abstract
Effectiveness of the adaptive method is widely known, when it is applied to the spatial axes. However, the method is not applied to the time axis in general. It is ideal if suitable time pitch fit well into each grid sizes. However, initial problem in time axis makes it difficult to be applied for adaptive method. In this report, we try to apply it to the spatial and the time axes simultaneously using implicit method for inner grid and explicit method for boundary grid in time step n+1/2.
