The impact of smooth W-grids in the numerical solution of singular perturbation two-point boundary value problems
This paper develops a semi-analytic technique for generating smooth nonuniform grids for the numerical solution of singularly perturbed two-point boundary value problems. It is based on the usual idea of mapping a uniform grid to the desired nonuniform grid. We introduce the W-grid, which depends on the perturbation parameter epsilon << 1. For problems on [0, 1] with a boundary layer at one end po
