Thank you. The transition to UFL sounds promising. May I ask at what stage that transition is now?


The new year is coming, I wish a happy new year for all the developers of FEniCS, you guys are great!

Best,
Chong

For example, for the file in the attachment, it takes more than two hours to compile (after two hours, I became impatient and killed the process). I've used "-r quadrature" switch, and my desktop is reasonablly fast (Intel Q6600+6G DDR2 1000).

This is a known issue with FFC for complicated forms. Hopefully it will be resolved after the transition to UFL since for quadrature code the UFL representation of forms should be more suitable.
