الوصف: If the problem of a long slender rod, impacting normally on a thick target, were to be solved on a computer by using a hydrodynamic code, it would soon be discovered that, because of computer memory limitations, the computational cells which describe the rod in the radial direction cannot be as plentiful as one would prefer for details in the penetration phenomena. Three computer runs were made using 2, 4, and 6 radial cells to describe a rod of 1 mm radius. Penetration, target hole growth, pressure and particle velocity histories, and shock wave propagation for these three cases were compared. Based on accuracy and the cost of the computer runs, it was found that the case which used four radial cells provided the most satisfactory tradeoff.
