摘要:

A computational technique is presented for designing a filter to improve the computational efficiency of a numerical scheme. For an explicit scheme, the integration time step is increased, causing several waves to become unstable. These waves are filtered without disturbing the accuracy of the solution and the accuracy of the remaining waves are controlled. The scheme is applied to the solution of the Euler equations by using the NPARC code.
