[petsc-users] How to use

[Sharp Stone]

Hi all,

I have four differential equations to be solved with a linear sparse matrix
system that has the form of "(mat)A dot (vec)X = (vec)B". For each node, I
have dof=4. I found few tutorials or examples on the KSPSolve with dof>1,
and I do know it's possible to solve this problem with Petsc. Are there any
sources illustrating ksp solver with dof>1? Many thanks!

Sorry for the stupid questions.
