Convergence of an adaptive hp finite element strategy in one space dimension
Abstract:
We show uniform decrease in energy error for an hp--adaptive algorithm with automatic hp selection on the elliptic model boundary value problem. The result is based on a new marking strategy for the finite element refinement. In case of a solution with algebraic singularity we demonstrate numerically that we achieve the known theoretical optimal exponential decrease of the error.
