Modeling, with a unified level-set representation, of the expansion of a hollow in the ground under different physical phenomena Cottereau, Regis; Díez, Pedro; Huerta, Antonio (2010)
Open AccessThis paper builds on the flexibility of the level-set representation to model in a unified manner the expansion of a hollow in the ground under different physical phenomena. In particular, the dissolving action of a flow ...
Strict error bounds for linear and nonlinear solid mechanics problems using a patch-based flux-free method Cottereau, Regis; Chamoin, Ludovic; Díez, Pedro (2010-12)
Open AccessWe discuss, in this paper, a common ux-free method for the computation of strict error bounds for linear and nonlinear Finite Element computations. In the linear case, the error bounds are on the energy norm of the error, ...
Cottereau, Regis; Díez, Pedro (2009-06-08T11:56:46Z)
Open AccessIn this paper, we derive, in the framework of the ux-free method, strict bounds for the energy norm of the error associated to a finite element computation. In that framework, and when using linear elements, the problems ...
