报告摘要:Solid-state dewetting (SSD), a widespread phenomenon in solid-solid-vapor system, could be used to describe the accumulation of solid thin films on the substrate. In this talk, we develop several structure-preserving parametric finite element approximations for the SSD. We focus on the mass conservation, the energy stability and the mesh quality of the numerical schemes. Finally, we present several numerical simulations to show accuracy and efficiency as well as some structure-preserving properties of the proposed numerical methods.
