Hi Fande,
It looks like SNESTestJacobian() in master is more reliable than that in
maint. Especially, the petsc options name is changed. For example, from
"-snes_test_jacobian_display" to "-snes_test_jacobian_view".
There are some MOOSE tests that fail with the maint version of
SNESTestJacobian(), but they are just fine with the master version of
SNESTestJacobian().
are you able to provide us with a standalone test that exposes the
problem so that we can fix it?
What is the release date for PETSc-3.10.x? I could just skip
PETSc-3.9.x, if we would have the next release soon.
Late September 2018.
Best regards,
Karli
