A Petrov-Galerkin finite element method for convection

WebJun 2, 2014 · We study a numerical method for convection diffusion equations, in the regime of small viscosity. It can be described as an exponentially fitted conforming Petrov-Galerkin method. We identify norms for which we have both continuity and an inf-sup condition, which are uniform in mesh-width and viscosity, up to a logarithm, as long as … WebRassurez-vous, le Crosswind Assist corrige automatiquement l’angle de la direction (à partir de 80 km/h). ...
