The main focus of this paper is to investigate the filtering operation for the finite element method in a LES (Large Eddy Simulation) with the dynamic sub-grid scale (SGS) model. A turbulent channel flow has been calculated using the present filtering operation based on characteristics of unstructured grids. The results have been compared with those of a finite difference method (FDM), and have verified applicability of the method.
