Abstract

We deal with the numerical solution of the semilinear convection-diffusion equation. The space discretization is carried out by discontinuous Galerkin finite element method and for the time discretization we employ suitable combination of implicit and explicit Runge-Kutta method. The resulting scheme is robust and very effective.
