[sfepy] Coupled phase field and linear elasticity

Hi,

I'd like to try and solve the problem outlined here,

https://pages.nist.gov/pfhub/benchmarks/benchmark4.ipynb/

Is this a problem that Sfepy could handle? I'm assuming the elasticity part of the problem would be straightforward, but what about a fourth order phase field equation? Given that it's tractable are there examples that match the form of the elasticity equation and/or any Cahn-Hilliard type examples for Sfepy?

Cheers,

Daniel
