N2 - We propose a novel shock-capturing method that is based on the ideas of characteristic filters and dynamic suboptimal control. A cost function is based on the smoothness of the solution, and formally minimized to obtain the unknown coefficient in the shock-capturing numerical fluxes. The proposed dynamic procedure is applied to one-dimensional Euler equation equation and two-dimensional Navier-Stokes equation. The proposed dynamic filter achieved noticeable success in capturing shock while minimizing the overall impact on the solution.
