Hello,
I am trying to solve the incompressible n-s equations by
PCFieldSplit.
The large matrix and vectors are formed by MatCreateNest()
and VecCreateNest().
The system is solved directly by the following command:
-ksp_type fgmres \
-pc_type fieldsplit \
-pc_fieldsplit_type schur \
other options that can help improve
the
pcfieldsplit performance.
Kind Regards,
Shidi

Hello Barry,
Thank you for your reply.
I reduced the tolerances and get desired solution.
