Abstract:

In this talk, we study the numerical solution of a sharp-interface model for the solid-state dewetting problem. We add an L1 curvature regularization to the interfacial energy functional in order to make this problem well-posed. This new regularization could improve the computational efficiency that can be observed in real experiments. Besides this, in this work, we also propose a new numerical scheme based on convex-splitting to solve the proposed model for the strongly anisotropic case, which could remarkably relax the restriction on the time step for solving the proposed model. Moreover, we provide theoretical analysis for the scheme and demonstrate the accuracy and high efficiency by numerical results.
