Optimal Adaptivity for the SUPG Finite Element Method
arXiv:1806.11000 · doi:10.1016/j.cma.2019.05.028
Abstract
For convection dominated problems, the streamline upwind Petrov--Galerkin method (SUPG), also named streamline diffusion finite element method (SDFEM), ensures a stable finite element solution. Based on robust a posteriori error estimators, we propose an adaptive mesh-refining algorithm for SUPG and prove that the generated SUPG solutions converge at asymptotically optimal rates towards the exact solution.
