Local recoarsements of finite element grids for solving the Navier-Stokes equations are investigated. The recoarsement algorithm is based on the hierarchic tri-tree multigrid generation algorithm and computes a local tri-tree element Reynolds number. A necessary condition for convergence is found to be that the element Reynolds number is less than 10.
