   Department of Computer Science, University of Waterloo:  "Finite
   element mesh generation for complex regions of the plane".

   ABSTRACT:  The goal of automatic discretization for problems
   involving partial differential equations is pursued in the finite
   element method by combining the capability to triangulate regions
   of the plane with the method's technique for generating discrete
   equations for general triangulations.  Hence a subgoal is to
   provide a mesh generation capability that is as automatic, general,
   and robust as the other components of the method, e.g. local
   stiffness matrix generation, or sparse matrix computations.  We
   present a method for triangulating regions with boundaries made up
   of one or more simple polygonal curves that attempt to serve
   this subgoal.

   In this context, a region has a complicated shape:  if there is
   a large variation in the lengths of its boundary segments and if
   a high proportion of its angles are not convex.  The method
   presented involves decomposing the region into convex subregions
   using computational geometry techniques, followed by further
   decomposition, based on desired triangle size distribution.
