DOUG

Description:

Domain decomposition On Unstructured Grids: a black-box parallel iterative solver for FE systems arising from elliptic pde's.

Author:

Mark Hagger at the University of Bath.

Platforms:

Will run in parallel on any machine which supports MPI. Has been tested on SGI, SUN, SUN Solaris, IBM SP/2 and Intel i860 architectures.

Availability:

More details and the code itself can be found at http://www.maths.bath.ac.uk/~parsoft/doug/

Notes:

DOUG makes no assumptions about the FE mesh: it takes as input basic topological information (eg from a mesh generator), and the finite element discretisation (stiffness matrix and RHS for each element). DOUG then applies a range of domain decomposition preconditioners and iterative methods to solve the linear system.
