UG is a software framework for the efficient
solution of partial differential equations
on unstructured grids.
Its
main features are robust multigrid
solvers for
unstructured, locally refined meshes,
parallel
multigrid methods, parallel online
visualization
and flexibility, which enables
it to be applied
to such diverse application
fields like Navier-Stokes
equations, elastoplasticity,
density driven flow andmultiphase
flow in porous media. UG contains a large
library of parallel solution
methods for linear, nonlinear
and time dependent problems
and a parallel grid manager
that is capable of local
refinement and coarsening of
unstructured meshes in two and
three space dimensions.
The reuse of this highly complex
functionality is the
key to enable the simulation of
large-scale physical
processes on modern supercomputers.
In ten years of
development UG has reached a
mature state and is used
in several institutions. Future
development directions
will consider greater modularization,
especially on
the level of problem class libraries
to allow for the coupling of different
partial differential equations
in one domain.
