<H1>curvature problem</H1>

 <P>If we use very high refinement orthogonal to a curved surface, we
need some minimal refinement in tangential direction too. Else, the
Delaunay grid becomes incompatible with the geometry.  As a
consequence, the geometry becomes incorrect (region cells intersecting
a boundary face):

 <P>The standard strategy is to use better refinement in tangential
direction in the problematic region. This strategy has been used
