International audience; The remapping strategy is crucial in any Arbitrary Lagrangian-Eulerian (ALE) algorithm based on a Lagrange-plus-remap paradigm. This step is particularly challenging for space-staggered schemes since inconsistencies may appear

In this paper, we propose a curve construction method for a non uniform point data set based on a minimal curve approximation model. Numerically, the level set method is used for curve reconstruction. We represent the shape of the curve through its d

In this paper, we focus on the problem of adapting dynamic triangulations during numerical simulations to reduce the approximation errors. Dynamically evolving interfaces arise in many applications, such as free surfaces in multiphase flows and movin

In this Note, we deal with the problem of constructing a regular (smooth) curve Γ such that ∀x∈Γ, d(x,V)⩽e, where d(x,V)=minx¯∈V‖x−x¯‖ for a given point cloud V assumed to belong to the boundary of an open subset of R2 and for e sma

The aim of this work is to develop an algorithm that allows the common renement of non-coincident meshes composed of arbitrary 3D surfaces elements (triangles, quad elements). This study is motivated by computations in geologic applications which inv

The aim of this paper is the numerical simulation of compressible hydrodynamic strong implosions, which take place for instance in Inertial Confinement Fusion. It focuses in particular on two crucial issues, for such calculations: very low CFL number

In this paper, we propose a nonlinear PDE model for reconstructing a regular surface from sampled data. At first, we show the existence and the uniqueness of a viscosity solution to this problem. Then we propose a numerical scheme for solving the non
