abstract = {A parallel Schwarz domain decomposition method for the
numerical solution of water flow in soils and aquifers is
presented. This method offers the possibility to solve large
numerical problems occurring by calculations of water flow
in heterogeneous porous media on parallel computer systems.
Strongly nonlinear problems requiring fine discretizations
in time and space can be handled. The method may easily be
incorporated in existing models with only slight changes in
the computer code. Communication routines are implemented in
such a way that they can be portated on various parallel
computer systems, ranging from workstation clusters to
massively parallel systems with distributed memory or vector
computers with several processors. The method was tested
using 3D homogeneous and heterogeneous flow domains with
9216 nodal points. A 3D finite element method was used to
solve the Richards equation in an unsaturated flow domain.
For runs on an Intel iPSC/860 and Paragon XP/S10 high
speedups and considerably reduced execution times compared
to the sequential version were achieved.},
