A stable XFEM formulation for multi-phase problems enforcing the accuracy of the fluxes through Lagrange multipliers Díez, Pedro; Cottereau, Régis; Zlotnik, Sergio (2013-11-02)
Open AccessWhen applied to diffusion problems in a multi-phase setup, the popular extended finite element method (XFEM) strategy suffers from an inaccurate representation of the local fluxes in the vicinity of the interface. The XFEM ...

Open AccessWe present an r-adaptivity approach for boundary value problems with randomly fluctuating material parameters solved through the Monte Carlo or stochastic collocation methods. This approach tailors a specific mesh for each ...

Open AccessWe present in this paper a numerical model of the erosion of a soil that accounts for both the flow in the open fluid and the flow of fluid through the porous soil. The interface between the open fluid and the soil is ...
