A note on a recent study of stabilized finite element computations for heat conduction

摘要

In a recent paper studying finite element computation of heat transfer processes with dominant sources, for which the classical Galerkin method proves unstable, the authors conclude that Galerkin/least-squares (GLS) stabilization is insufficient while Galerkin-gradient/least-squares (GGLS) stabilization provides good results. It is the intention of this manuscript to correct these conclusions, that are based on a GLS method with a suboptimal parameter and on mislabelling a combined stabilized method as GGLS.
