[petsc-users] SNES test with a nested matrix

[Norihiro Watanabe]

Hi, I wonder whether "-snes_type test" option can work also with a nested
matrix. I got the following error in my program and am not sure if there is
a problem in my codes or just PETSc doesn't support it.


Testing hand-coded Jacobian, if the ratio is
O(1.e-8), the hand-coded Jacobian is probably correct.
Run with -snes_test_display to show difference
of hand-coded and finite difference Jacobian.
