Pass the right UFL element to the Klein map.
Minor fixes for 1.3 for Gross-Pitaevskii equation
First stab at the PCD case from Kay (2002).
Elimination of the pressure BCs makes it much better.
Fiddling with the setup a little.
Didn't need CG in the end (they aren't singular now)
Indeed, as the mesh is refined, the number of preconditioner actions decreases. Interesting!
Playing around with the PCD. Use LU for the matrices that never change, but use ML for the upper-left block.
Some cleanups of the salt fingering GST
Lots of documentation for salt_fingering.py.
