We consider an upwind ÿnite di erence scheme on a novel layer-adapted mesh (a modiÿcation of Shishkin's piecewise uniform mesh) for a model singularly perturbed convection-di usion problem in two dimensions. We prove that the upwind scheme on the modiÿed Shishkin mesh is ÿrst-order convergent in the

We stud here a finite volume scheme for a diffusion-convection equation on an open bounded set presented along with the geometrical assumptions on the mesh. An error estimate of order h on the discrete L2 norm is obtained, where h denotes the "size" of the mesh. The proof uses an estimate of order h
The cell discretization algorithm is applied to generate approximate solutions for some second-order non-self-adjoint elliptic equations. General convergence for homogeneous problems is shown by obtaining suitable error estimates. The method is applied using polynomial bases; this provides a nonconf
