In this paper a penalty finite element solution method for the unsteady Navier-Stokes equations for two-dimensional incompressible flow is described. The performances of the Euler implicit (El) and the Crank-Nicolson (CN) time integration methods are analysed. Special attention is payed to the undam

A mixed finite element-boundary element solution for the analysis of two-dimensional flow in porous media composed of rock blocks and discrete fractures is described. The rock blocks are modelled implicitly by using boundary elements whereas finite elements are adopted to model the discrete fracture
## Abstract In this article we analyze a finite element method for threeโdimensional unsteady compressible NavierโStokes equations. We prove the existence and uniqueness of the numerical solution, and obtain __a priori__ error estimates uniform in time. Numerical computations are carried out to tes
