We propose inf-sup testing for รฟnite element methods with upwinding used to solve convection-di usion problems. The testing evaluates the stability of a method and compactly displays the numerical behaviour as the convection e ects increase. Four discretization schemes are considered: the standard G

This paper addresses the evaluation of the inf-sup condition for Reissner-Mindlin plate bending elements. This fundamental condition for stability and optimality of a mixed รฟnite element scheme is, in general, very di cult to evaluate analytically, considering for example distorted meshes. Therefore
