Does anyone have any experience on Domain Decomposition using PETSc library? I have used PETSc for creating my vectors and matrix within my c++ code. I also used KSP to solve the linear system. I used follwoing examples tp learn about DD in PETSc but they were not helpful for me:
http://www.mcs.anl.gov/petsc/petsc-3.5/src/snes/examples/tutorials/ex10d/ex10.c.html http://www.mcs.anl.gov/petsc/petsc-3.2/src/snes/examples/tutorials/ex12.c.html http://www.mcs.anl.gov/petsc/petsc-current/src/snes/examples/tutorials/ex62.c.html
I would be grateful if you give me some hints on how to do the graph partitioning and domain decomposition with PETSc.
