Efficient and simple fourth-order compact finite difference methods for convection-diffusion-reaction equations on arbitrary curved domains
Qiwei Feng, Bin Han, Peter Minev
In this paper, we discuss the 2D convection-diffusion-reaction equation with variable smooth coefficients and the Dirichlet boundary condition on a complicated, thin, and curved do…

Fourth-order compact finite difference methods for 2D and 3D nonlinear convection-diffusion-reaction equations
Qiwei Feng
In this paper, we first consider linear 2D and 3D convection-diffusion-reaction equations and $u_t - \nabla\cdot (κ\nab…
