libpsurface-dev - 2.0.0-2+b1 main

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.
