Publication number: 20170177771Abstract: Embodiments provide methods and systems for modifying a finite element mesh representation of a three-dimensional model. A method according to an embodiment defines a symmetric constraint of a finite element mesh where the finite element mesh represents a subject 3D model and the symmetric constraint comprises two asymmetric zones of the finite element mesh to be modified symmetrically. Next, corresponding finite elements between the two asymmetric zones are identified and a topological manipulation to at least one of the identified corresponding finite elements is performed. In response, the topological manipulation is performed symmetrically on the identified finite element corresponding to the at least one finite element. In such an embodiment, performing the manipulation symmetrically results in the two asymmetric zones being modified symmetrically and represents a symmetrical topological modification in the subject 3D model.Type: ApplicationFiled: August 16, 2016Publication date: June 22, 2017Inventors: Frederic Letzelter, Jean-Marc Chauvet, Christophe Dufau
