Abstract

We introduce a method for treating general boundary conditionsin the finite element method generalizing an approach, due toNitsche (1971),for approximating Dirichlet boundary conditions. We use Poisson’s equationsas a model problem and prove a priori and a posteriori error estimates. Themethod is also compared with the traditional Galerkin method. The theoreticalresults are verified numerically.

    Uncommonly clear description of the method, the error analysis, the benchmark problem, &c., &c.; ideal for someone wishing to reproduce the results. Commendable.
