Numerical Simulation of Grain-Boundary Grooving by Level Set Method
A numerical investigation of grain-boundary grooving by means of a level set method is carried out. An idealized polycrystalline interconnect which consists of grains separated by parallel grain boundaries aligned normal to the average orientation of the surface is considered. Initially, the surface diffusion is the only physical mechanism assumed. The surface diffusion is driven by surface-cur...

Keywords: Drop pinch-off Level set methods Boundary integral methods Non-viscous flow Potential flow a b s t r a c t Simulations of the pinch-off of an inviscid fluid column are carried out based upon a potential flow model with capillary forces. The interface location and the time evolution of the free surface boundary condition are both approximated by means of level set techniques on a fixed...
متن کاملA Two-Dimensional Study of Coupled Grain Boundary Motion using Level Set Method
The coupled motion of a closed non-circular grain boundary (GB) in a bicrystal, with both isotropic and anisotropic GB energies, is studied using the level set method. The kinetic relations, obtained within the framework of linear irreversible thermodynamics, govern the overall dynamics including normal motion (migration) of the GB, viscous sliding along the GB, and tangential motion of the gra...
متن کاملGrooving of a grain boundary by evaporation–condensation below the roughening transition
The development of surface grooves at grain boundaries that intersect a planar surface is analyzed for the case that the evolution occurs below the thermodynamic roughening transition by evaporation–condensation processes. The dynamics are described by a nonlinear partial differential equation that has a similarity solution, so the resulting groove profile is described by a nonlinear ordinary d...
متن کاملLevel set modeling of transient electromigration grooving q
A numerical investigation of grain-boundary (GB) grooving by means of the level set (LS) method is carried out. GB grooving is emerging as a key element of electromigration (EM) drift in polycrystalline microelectronic (ME) interconnects, as evidenced by a number of recent studies. The purpose of the present study is to provide an ecient numerical simulation, allowing a parametric study of the...
