The rate of convergence of the finite element method is greatly influenced by the existence of corners on the boundary. The paper shows that proper refinement of the elements around the corners leads to the rate of convergence which is the same as it would be on domain with smooth boundary. Die Konvergenzgeschwindigkeit der Methode der endlichen Elemente… CONTINUE READING
