[petsc-users] Differential operators in PETSc

[Alexander Grayver]

Jed,

I would like to discuss it, but I'm afraid I can't pose right questions 
due to the lack of wide knowledge regarding problem, since my 
understanding and motivation is only within my problem, which is vector 
Helmholtz equation.
Would anybody more experienced like to start this discussion?

Regards,
Alexander
