In this thesis, we propose a characteristic tailored finite point method (CTFPM) in solving the convection-diffusion-reaction equation with variable convection coefficients. Our numerical tests show for small diffusion coefficient the CTFPM solution resolves the internal and boundary layers in size of O(epsilon) regardless the mesh size, and depicts that CTFPM method in the streamline grid has excellent performance in comparing with tailored finite point method and some well-known finite element methods when epsilon is small.
