This extension is based in a hierarchical ordering of several level set functions. To complete the X–FEM approach, the enrichment via partition of the unity method is also extended. The ridge function, base of the enriched interpolation, is restated to include several level sets and the hierarchy between them. dc.format.extent 11 p. dc.language.iso eng dc.relation.ispartof NMASE 07 (6th:2007:Vall de Núria) dc.rights Attribution-NonCommercial-NoDerivs 3.0 Spain dc.rights.uri http://creativecommons.org/licenses/by-nc-nd/3.0/es/ dc.subject Àrees temàtiques de la UPC::Matemàtiques i estadística::Equacions diferencials i integrals::Equacions en derivades parcials dc.subject.lcsh Partial differential equations dc.subject.other Multiphase flow dc.subject.other Level set methods dc.subject.other Enrichment dc.subject.other Extended finite element method (X-FEM) dc.title Hierarchical x-fem applied to n-phase flow dc.type Conference report dc.subject.lemac Equacions diferencials parcials dc.subject.lemac Problemes de valor inicial dc.subject.lemac Problemes de contorn dc.subject.ams Classificació AMS::65 Numerical analysis::65M Partial differential equations, initial value and time-dependent initial-boundary value problems dc.rights.access Open Access
