[petsc-users] Error Norm_2

[Fazlul Huq]

Hello PETSc Developers,

I have solved a very simple poisson problem with different matrix sizes (10
to 10^7).
But when I have compared error norm_2 for the solution, I got the attached
curve.
It looks like error norm_2 increases with increasing matrix size. Shouldn't
it decrease rather with increasing matrix size?

Thanks.

Sincerely,
Huq
