| Abstract: |
| In this article,we study numerical simulation of one-dimensional linear SchrÖodinger wave equation with non-uniform space mesh.The non-uniform mesh will generate the spurious reflection at the interface in numerical simulation,by using locate time stepping method and proper interface condition,we can effectively reduce the spurious reflections at the interface.The interface condition can significantly improve the efficiency and precision in numerical simulation. |
