[petsc-users] PCFIELDSPLIT question

[Hom Nath Gharti]

Dear all,

I am new to PcFieldSplit.

I have a matrix formed using MATMPIAIJ. Is it possible to use
PCFIELDSPLIT operations in this type of matrix? Or does it have to be
MATMPIBIJ or MATNEST format?

If possible for MATMPIAIJ, could anybody provide me a simple example
or few steps? Variables in the equations are displacement vector,
scalar potential and pressure.

Thanks for help.
