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 following examples to learn about Domain Decomposition in PETSc but they were not helpful:
I would be grateful if you give me some hints on how to do the graph partitioning and domain decomposition with PETSc.
