Yes, assemble() in PyDOLFIN currently assumes that you give it an FFC
form and a Mesh. It then calls the JIT compiler on the form and then
calls the wrapped C++ assembler on the generated UFC code.

Does it work if you use cpp_assemble() instead of assemble()?

We should try and extend assemble() in Python so it can recognize
various combinations of input arguments (an FFC form or a UFC etc).

The assemble() function is just a few lines of code and it's defined
in assemble.py in src/pydolfin/.
