[petsc-users] snes test fails

[Dharmendar Reddy]

Hello,
         I am solving a one dimensional (linear) Poisson equation. I have
setup a snes problem using DM object. I am using Dirichlet boundary
conditons at both ends of the one dimensional domain. For the test case i
use the same value for potential at both ends.

I am using DMplex object for the mesh and dof lay out.

If i run the solver, i get a constant potential profile as expected.
However, If i run the solver with snes_type test
It is giving an error. what could i have done wrong ?

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.
Norm of matrix ratio 1.0913e-10 difference 5.85042e-10 (user-defined state)
Norm of matrix ratio 0.5 difference 5.36098 (constant state -1.0)
Norm of matrix ratio 0.666667 difference 10.722 (constant state 1.0)
