Mar 1, 2021 · For Dirichlet boundary conditions, we estimate the error when the boundary values are imposed through the boundary penalty method.
Our analysis of the boundary penalty method relies on the Friedrich inequality which states that the L2(Ω) norm of a function can be estimated by the norm of ...
