Résumé

This work is in the field of multimaterial compressible fluid flows simulation. The proposed scheme is eulerian and related to finite volumes methods, but in a Lagrange-Remap formalism on cartesian orthogonal meshes. The lagrangian scheme is staggered and the remap phase is similar to a finite volume advection scheme. The multimaterial extension uses classical VOF fluxes for sharp interface reconstruction. The originality of the scheme is in the attempt for a multimaterial 9 points multimaterial scheme without directional splitting. This strategy should allow to preserve good properties of classical multimaterial schemes, saving parallel communications with the one step remap. Results will be discussed and compared to those from classical lagrange-remap schemes on severe benchmarks.
