On dynamic computational subgrid modeling
In this paper we study a subgrid model based on extrapolation of a corrective force, in the case of a linear convection-diffusion problem $Lu=f$ in one dimension. The running average $u^{h}$ of the exact solution $u$ on the finest computational scale $h$ satisfies an equation $L_{h}u^{h}=[f]^{h}+F_{...
