Efficient energy-stable parametric finite element methods for surface diffusion flow and applications in solid-state dewetting
Meng Li, Yihang Guo, Jingjiang Bi
Currently existing energy-stable parametric finite element methods for surface diffusion flow and other flows are usually limited to first-order accuracy in time. Designing a high-…

Structure-preserving weighted BDF2 methods for Anisotropic Cahn-Hilliard model: uniform/variable-time-steps
Meng Li, Jingjiang Bi, Nan Wang
In this paper, we innovatively develop uniform/variable-time-step weighted and shifted BDF2 (WSBDF2) methods for the anisotropic Cahn-Hilliard (CH) model, combining the scalar auxi…
