A warning is printed by the PETsc solver that it did not converge, but I can't seem to find a way to detect this programatically. The solve method returns a Function even if the solver did not converge.

Just an error is bad. Presently, a warning message is printed, but we 
can add a parameter to switch between error/warning.
