Hello All, I'm interested in solving a PDE involving a 4th order derivative (specifically, the 4th order phase-field model proposed by Borden et al. 2014). <http://www.sciencedirect.com/science/article/pii/S0045782514000292>I believe such equations require C1 continuous elements but this is challenging due to lower order of continuity at element boundaries. It seems that this issue has been discussed in a previous thread <https://groups.google.com/forum/#!topic/dealii/y-Jnn4uuSsY> and deal.II yet supported such elements.
I just wonder if this is still the case. Using isogeometric elements appear a good way to resolve this issue, and I think there has been recent progress in supporting isogeometric analysis in deal.II. I'm novice in this aspect though, and would greatly appreciate any advice on this matter. My goal is to extend the current solver for the 2nd-order phase-field model to the 4th-order one, with minimal efforts. Thanks very much!
