PETSc + HYPRE

[Márcio Ricardo Pivello]

Hi, Lisandro. I must apologize for not answering. I read your email and
changed my code, but then I went through a different path. I'm trying to
call the preconditioner from the command line, without any mention to it in
the source code. It should take a couple of hours to get some results and
then, if it doesn't work, I'll change the code.


Thank you very much.


Márcio Ricardo
