Numerical Solution of a Singularly Perturbed Problem on a Circular Domain

Numerical Solution of a Singularly Perturbed Problem on a Circular Domain

We consider a singularly perturbed elliptic problem, of convection-diffusion type, posed on a circular domain. Using polar coordinates, simple upwinding and a piecewise-uniform Shishkin mesh in the radial direction, we construct a numerical method that is monotone, pointwise accurate and parameter-un...
