Abstract
Under the DoD High Performance Computer Modernization Program, the
ARDEC Energetics and Warheads Division has successfully developed and
demonstrated scalable parallel warhead mechanics modeling of an advanced
explosively formed penetrator (EFP) warhead device. Warhead development
commonly uses advanced computer modeling which can take extreme amounts
of computer time. The recent application of scalable parallel computers has
demonstrated the capability to achieve approximately a 120 times speed-up of
EFP warhead modeling. Speed-ups were demonstrated using modeling of a
copper lined EFP anti-armor warhead using the PCTH computer program on a
number of multiple processor computers including a 256 node IBM SP2, 128
node Silicon Graphics Origin 2000 and smaller multiple processor Silicon
Graphics workstations. This pioneering work clearly demonstrates the feasibility
of applying parallel computers for warheads development.
Keywords: explosively formed penetrator, scalable computing, parallel
computing.
1 Background
Continuum simulation of high rate explosive applications using finite element,
finite difference and discrete particle methodologies have received considerable
attention since the advent of digital computers (Von Neumann and Richtmyer
[1], Mader [2], Wilkins [3]). Explicit high rate continuum simulation is
extremely computationally intensive. As a result, less computationally
demanding analytic models of high explosive systems have been widely
developed and used (Baker [4], Yates et al [5]). However, analytic models rely
