摘要
This paper is devoted to the numerical solution of the scalar convection–diffusion equation. We present new results of the adaptive technique in finite element method based on minimizing a functional called error indicator. Particularly, we use more different spaces (space of piecewise constant functions, piecewise linear continuous functions, and piecewise linear discontinuous functions) for the parameter τ from the SUPG (SDFEM) method.
