Frontiers of Mechanical Engineering 2019, Volume 14, Issue 2,   Pages 222-234 doi: 10.1007/s11465-019-0534-1

Abstract: In this study, we develop an isogeometric analysis (IGA)-based level set model for the formulation andThe proposed method is based on a combination of level set method and IGA technique, which uses the non-uniformrational B-spline (NURBS), description of geometry, to perform analysis.The same NURBS is used for geometry representation, but also for IGA-based dynamic analysis and parameterizationof the level set surface, that is, the level set function.
