I would look at some PETSc examples, for instance http://www-unix.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/src/ksp/… Matt On 3/31/07, Waad Subber <wsubber(a)connect.carleton.ca> wrote: > Hello everyone: > > I am new to PETSC.

There seems to be no study too fragmented, no hypothesis too trivial, no literature citation too biased or too egotistical, no design too warped, no methodology too bungled, no presentation of results too inaccurate, too obscure, and too contradictory, no analysis too self-serving, no argument too circular, no conclusions too trifling or too unjustified, and no grammar and syntax too offensive for a paper to end up in print. -- Drummond Rennie

DDM with PETSc

Hello everyone: I am new to PETSC. Reading the tutorials, I understand that PETSC supports domain decomposition with additive Schwartz and iterative substructuring (balancing Neumann-Neumann). I am looking for some example codes involving these domain decomposition methods for 1D and 2D PDE (preferable linear PDE) so that I can get started. Can anyone kindly point me to the right place where I can find them. Thanks :) waad

mpirun --> mpiexec in petsc-dev

I have updated the PETSc-dev src/bin/configure.py to use mpiexec/MPIEXEC instead of mpirun/MPIRUN as the variable names. program names etc. Let us know if this introduces any problems. Barry
