Accurate triangulation of the domain plays a pivotal role in computing the numerical approximation of the differential operators. A good triangulation is the one which aids in reducing discretization errors. In a standard collocation technique, the s

This paper demonstrates non-uniform mesh generation scheme for two-dimensional domains. For many models in fluid dynamics like turbulent flow, channel flow there is large gradient in the small narrow portion, for example near the wall region. To solv

A MATLAB code for generation of curved triangular elements in two dimensions is presented. The method is based on the MATLAB meshing scheme distmesh2d provided by Persson and Strang. The meshing scheme generates triangular meshing for three symmetric
