Ugh, one of the recent changes we made was to turn on COFFEE's optimisations by default.  Unfortunately, this has led to some teething problems.

I assume that all components -- COFFEE, Firedrake, PyOP2, FFC, UFL, and FIAT -- are up to date, and that you're running with a clean cache (from the Firedrake base directory, run "./scripts/firedrake-clean").

If the problem persists, as a short-term workaround, can you add

op2.init()
parameters["coffee"]["O2"] = False

to the start of your file, just after the imports?  This will result in sub-optimal performance during the assembly stage, so isn't ideal in the long-term.

Fabio, our resident barista, will have some fixes after the new year, I'm sure.

Dear all,

I very recently updated firedrake, pyop2 and installed coffee, but since then none of my codes include nonlinear solvers don’t work (they used to work fine before the update).

I even tried to run the burgers.py code from the demo and even that diverges.

I get something like:
