Fortin operator
WebApr 3, 2008 · A standard method for proving the inf-sup condition implying stability of finite element approximations for the stationary Stokes equations is to construct a Fortin operator. In this paper, we show how this can be done for two-dimensional triangular and rectangular Taylor-Hood methods, which use continuous piecewise polynomial … Webdimensional approximation to the test space. Such a map is called a Fortin operator [1][2]. We highlight the construction of a DPG Fortin operator for H 1 and H(div) spaces, focusing on a uniform triangular 2D mesh. We present sufficient conditions to ensure the uniqueness of the Fortin operator for the H1 and H(div) cases, using the

We then develop a line of argument based on the direct construction of a global Fortin operator; we find that employing a poly-nomial enrichment for the test space does not suffice for this purpose, motivating the introduction of a (two-element) subgrid mesh.
