We examine the discrete free boundaries arising from a finite element
discretization of a variational inequality. We give L∞ error bounds
for the Hausdorff distance of the discrete and true free boundary,
as well as for the normals. The theoretical results are confirmed
by numerical experiments in two and three dimensions.
