Abstract : This report was prepared as a user manual for implementing the vectorized Elastic/Plastic HULL (EPHULL) Composite HULL code and SAIL code on the AFWL CRAY computer. Major programs required to operate the Composite HULL code and supporting programs and files on the AFWL CRAY are described. The Composite HULL code developed through this work is usable over the range of problems formerly accommodated by either Vector HULL or EPHULL, and is simpler and less time-consuming for new users to learn. The Cylinder In Situ Test (CIST) Equation of State (EOS) in this manual was rewritten from the California Research Arbitrary Lagrangian-Eulerian (CRALE) code for use with a variety of soils. Keywords: HULL, Elastic-plastic, Hydrocode, Fluid dynamics, Equations-of-state, CTSS, BOW, Airblast prediction, Numerical modelling, EPHULL, Computer codes, Hydrodynamics, Finite difference.
