I'd like to try and solve the problem outlined here,
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?
I have no experience with that kind of equation. However, I have found an article mentioning that the fourth order equation can be solved by splitting into two second order equations . That should be doable with sfepy, talking about assembling the problem and getting the discretized system (if H1 elements are OK). Again, I have no experience with solving such systems.
