Description
I'd like to experiment some advanced diagnostic techniques for debugging nonlinear solver failures at initialization.
To do so, I need to figure out for each nonlinear implicit system of equations on which tearing variables the Jacobian depends on, directly, or indirectly through the torn equations.
I understand from today's discussion in the webmeeting that this information is already available. Can you please dump it somehow, in terms of a list of variable names and/or a list of indeces in the unknown vector x?
Thanks!

Retargeted to 1.18.0 because of 1.17.0 timed release.

for help on using tickets.
Releasing 1.14.0 which is stable and has many improvements w.r.t. 1.13.2. This issue is rescheduled to 1.16.0
