Example of Verification Analysis for an Eulerian Hydrocode (U).

[摘要] An important activity in the process of code development is code verification, by which we mean detailed examination of and numerical demonstration that the equations are being solved correctly. This process can entail the comparison of code calculations for problems that possess analytic or quasi-analytic solutions. In this presentation we provide results of a verification analysis of the RAGE hydrocode for two particularly challenging problems: (1) the pure hydro-dynamic problem of an adiabatically compressing region, and (2) the coupled hydrodynamics/conduction problem of Reinicke & Meyer-ter-Vehn. We present companson of code results with the analytic solutions and convergence rates for these cases.
