[petsc-users] Any Examples for 3D Poisson Solver with both Dirichlet and Neumann BC's

[TAY wee-beng]

Hi,

Does anyone has experience of the performance of this solver with Hypre 
multigrid solvers? I'm now using Hypre struct solver and wonder if it is 
worth trying out other multigrid solvers.

Yours sincerely,
