Abstract:
Adaptive grid techniques through a variational approach are applied to two shock problems with exact solutions.More grid points are redistributed in the shock regions in response to numerical solution and thus the shock can be captured successfully.The results show the techniques have excellent qualities in improving accuracy of numerical solution and reducing CPU time.

Key words:
adaptive grid techniques; shock
