In this paper a variational multiscale method based on local projection and grad-div stabilization for LargeEddy simulation for the incompressible Navier-Stokes problem is considered An a priori error estimate is given for a case with rather general nonlinear (piecewise constant) coefficients of the subgrid models for the unresolved scales of velocity and pressure Then the design of the subgrid scale m
