| Abstract: | This paper deals with the penalty non linear Galerkin method with an aim at the initial boundary value problem of two dimensional transient incompressible Navier Stokes equations in the case of the finite elements, and also presents a general solution pattern. This makes the approximation errors be diminished fast and steadily and also approximates the numerical solution to the accurate solution fast. |
