Abstract :
Owing to the static and nonconformal mesh it employs, the level-set method for geometry representation offers several attractive alternatives for boundary movement and finite element schemes in comparison with conformal boundary representation. For boundary movement problems, the adaptive gridding schemes for the level-set method are analyzed for their applicability to tracing thin-film characteristics. For finite element schemes on non-interface-conformal mesh, advantages for additional trial functions based on the level-set function are illustrated by solving a partial differential equation on a geometry with rough interface.
