- W56530449 abstract "The Finite Element Method (FEM) is currently widely used for the numerical so-lution of boundary value problems de ned by Partial Di erential Equations. It hasbeen successfully applied in many areas of applied sciences and engineering. Nev-ertheless, standard FEM are not well suited for some applications such as problemswith moving boundaries or interfaces. In those problems standard FEM requiresthe mesh to be adapted to the interface or moving boundary, requiring continuousremeshing as time evolves, leading to high computational cost and lost of accuracydue to the projection of the solution from one mesh to another.eXtended Finite Elements (X-FEM) overcome this limitation. X-FEM is able tohandle interfaces and boundaries inside the nite elements, getting rid of the adap-tation of the mesh. The computational mesh covers the domain and (1) the solutionis enriched to describe discontinuities inside the elements, (2) the numerical inte-gration in each element is adapted to integrate only inside the domain. X-FEMis currently a widely used technique for the solution of problems with cracks, two-phase ow problems or problems with voids.This work focuses on problems with voids. In this case no re nement is neededand attention focuses on adapting the numerical integration. A computation meshincluding the domain and not adapted to the voids boundary is considered. A levelset function is used to de ne the interface corresponding to the voids boundaries.Using the level set value at the nodes, elements are classi ed as: interior, in voidor cut by the interface (the void boundary). For interior elements standard FEMintegration is used, elements inside the void are not considered for integration anda special numerical quadrature is de ned for elements cut by the interface. Eachelement cut by the interface is split in subtriangles and a numerical quadrature isconsidered for the subtriangles in the domain.In this work an X-FEM code for voids has been developed from a standard FEMcode. The developed routines aim to be a library for the X-FEM solution of two-phase ow problems." @default.
