Verification and Validation of LAD2D Hydrocodes for Multi-material Compressible Flows

Abstract

Lagrangian Hydrocodes is the main simulation tool in multi-material compressible flows of high temperature and high pressure. The important problems we are up against are how be should confidence in modeling and simulation be critically assessed. The verification and validation (V&V) of computational simulations are the primary methods for building and quantifying this confidence. Verification is the assessment of the accuracy of the solution to a computational model by comparison with known solutions. Validation is the assessment of the accuracy of a computational simulation by comparison with experimental data. In this paper, The verification and validation (V&V) of Lagrangian Hydrocodes of multi-material compressible flows was present. Verification of the LAD2D Software was implemented by the Sod problem. Validation of the LAD2D Software was implemented by the cylinder test.
