报告摘要
This talk is devoted to numerical methods for solid-state dewetting of thin films. Solid-state dewetting belongs to a class of interface problems and the motion of the (film/vapor) interface is governed by surface diffusion and contact line migration. We first review several methods for solving its sharp-interface model, including the “Marker- Particle” method and the parametric finite element method. Then we propose a new approach which can both reduce the stiffness from surface diffusion and improve the performance in mesh equidistribution.
