[petsc-users] MatZeroRows question

[Felipe Giacomelli]

 Hello,
According to PETSc documentation, all processes that share the matrix MUST
call this routine for the parallel case. However, it is possible that,
after the domain decomposition, some subdomains wouldn’t have Dirichlet
boundary conditions. Hence, MatZeroRows wouldn’t be called by all
processes. Is there a standard (or proposed) approach for this scenario?

Thank you,
