Abstract:

In this paper a piecewise linear finite element approximation of $H$-surfaces, or surfaces with constant mean curvature, spanned by a given Jordan curve in $\textbf {R}^3$ is considered. It is proved that the finite element $H$-surfaces converge to the exact $H$-surfaces under the condition that the Jordan curve is rectifiable. Several numerical examples are given.
