HYDROCODE TEST PROBLEMS

Abstract

The utility (accuracy, speed, etc.) of a hydrocode in solving the equations of hydrodynamics may be estimated by applying the hydrocode test problems described in this report. Given the estimations of the utilities of a pair of hydrocodes, one may decide which is the preferred hydrocode to use. The hydrocode test problems described in this report have solutions which are known exactly. Seven hydrocode test problems involving shocks, rarefactions, and interactions are investigated and applied to a typical hydrocode, AFWL's PUFF.
