- Domain decomposition On Unstructured Grids: a
black-box parallel iterative solver for FE systems arising from
at the University of Bath.
- 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.
- More details and the code itself can be
- 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.
