Eulerian/Lagrangian Sharp Interface Schemes for Multimaterials

Abstract : 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 materials. In the models considered, the gas, liquids, or elastic materials are described by specific constitutive laws, but the governing equations are the same. Examples of gas–gas and gas–elastic material interactions in one- and two-spatial dimensions are presented.
