Hi again, Daniel. Thanks for the advice. I’ve considered working with Sfepy and I’ll keep it in mind. I bought lecture notes for FEniCS recently, so I’ll work with that one for now.
I don’t entirely understand the derivation of the equations I’m working with. But the physical problem is wrinkling of a thin-film of some material on top of a visco-elastic substrate. The system is subjected to some initial stress. Through coupling at the interface of the thin-film and substrate, the initial stress and difference in the elasticities of the film and substrate, wrinkles can form. So yeah, it’s definitely related to linear elasticity problem. Would you send a paper or reference for the linear elasticity problem you were working on? I hope you get time soon to work on these issues! Thanks, Kyle.
