Accurate Sharp Interface Scheme for Multimaterials
TypeCommunications avec actes
We present a method to capture the evolution of a contact discontinuity separating two different material. A locally non-conservative scheme allows an accurate and stable simulation while the interface is kept sharp. Numerical illustrations include problems involving fluid and elastic problems.

GORSSE, Yannick; IOLLO, Angelo; MILCENT, Thomas (Springer Berlin Heidelberg, 2014)We present multimaterial simulations using both Eulerian and Lagrangian schemes. The methods employed are based on classical Godunov-like methods that are adapted to treat the case of interfaces separating different ...
GORSSE, Yannick; IOLLO, Angelo; MILCENT, Thomas; TELIB, Haysam (Elsevier, 2014)We present a simple numerical method to simulate the interaction of two non-miscible compressible materials separated by an interface. The media considered may have significantly different physical properties and constitutive ...
DE BRAUER, Alexia; GORSSE, Yannick; IOLLO, Angelo; MILCENT, Thomas (2013)We aim to simulate the interactions at the material interface of two compressible media. These interactions are modeled by a single fully Eulerian system of conservation laws. The materials differ by their constitutive ...
BRAUER (DE), Alexia; IOLLO, Angelo; MILCENT, Thomas (2014)This paper is devoted to the 3D extension of a sharp interface multimaterial method. We present preliminary results for 3D stiff cases of shock air/helium/water interaction and impacts of projectiles on elastic bodies ...
MILCENT, Thomas; IOLLO, Angelo (2013)We present multi-material simulations in the Lagrangian framework. The methods employed are based on classical Godunov-like methods that are adapted to treat the case of interfaces separating different materials. In the ...
