  Description     : piecewise linear bijections between triangulated surfaces

 Psurface is a C++ library that handles piecewise linear bijections
 between triangulated surfaces. These surfaces can be of arbitrary
 shape and need not even be manifolds.

 There are two main uses for psurface. When doing adaptive finite
 element simulations on grids with parametrized boundaries, psurface
 can store the parametrization. Boundary parametrizations are
 practically mappings from the coarse grid boundary to the actual
 boundary, and if that actual boundary is a triangulated surface then
 psurface can handle it. This is implemented, for example, in the
 dune-grid module of Dune.

 Secondly, when doing domain decomposition methods with nonconforming
 interfaces, you need to relate the two interface grids to each
 other. Psurface can do this for you, even if your interfaces do not
 match geometrically. Such is the case, e.g., in contact
 problems. This second functionality is also available for 1d surfaces
 in 2d space.

 The easiest way to use psurface for domain decomposition is to get
 the dune-grid-glue module and use it to drive psurface.

The package will be maintained in the science team.
