Adjoint action is zero in point discharge demo #188

Open ddundo opened 2 months ago

ddundo commented 2 months ago

If we run the point_discharge2d.py demo with get_adj_values=True, warnings are raised:

WARNING GoalOrientedMeshSeq: Adjoint action for field 'c' on 0th subinterval is zero.

This is the problem I tried to describe in #153.
