A Penalty-Free Asymmetric Nitsche's Method for Edge Elements
Abstract
We show the stability of a penalty-free asymmetric Nitsche's method using Nédélec edge elements for solving curl-curl-type problems with tangential Dirichlet boundary conditions imposed weakly. The main result is an inf-sup stability estimate for the asymmetric bilinear form under an isolated patch condition on the tetrahedral mesh. Applications to a curl-elliptic problem and a magnetic advection-diffusion problem are discussed.
