KWIC TITLE:Explicit 3-D Hydrodynamic FEM Program 
AUTHORS:Jerry Lin

DESCRIPTION:DYNA3D is a nonlinear explicit finite element code for analyzing 3-D structures and solid continuum. The code is vectorized and available on several computer platforms. The element library includes continuum, shell, beam, truss and spring/damper elements to allow maximum flexibility in modeling physical problems. Many materials are available to represent a wide range of material behavior, including elasticity, plasticity, composites, thermal effects and rate dependence. In addition, DYNA3D has a sophisticated contact interface capability, including frictional sliding, single surface contact and automatic contact generation. 
PACKAGE CONTENTS:Media Directories for DYNA3D2000* and DIGLIB; Procedures to make DYNA3D Executables; Software Abstract for DYNA3D2000* and DIGLIB; Installation Guides for SUN, and IBM; DYNA3D Code Practices and Developments (UCRL-ID-138654); Media Includes DYNA3D User Manual (UCRL-MA-107254), Media Directories, Source Codes, and Sample Problems for DYNA3D2000* and DIGLIB;\ 1 CD ROM 
SOURCE CODE INCLUDED?
MEDIA QUANTITY:
METHOD OF SOLUTION:Discretization of a continous model transforms partial differential equations into algebraic equations. A numerical solution is then obtained by solving these algebraic equations through a direct time marching scheme. 
COMPUTER:MLT-PLTFM 
OPERATING SYSTEMS:UNIX and UNICOS 
SOFTWARE LIMITATIONS:Recent software improvements have eliminated most of the user identified limitations with dynamic memory allocation and a very large format description that has pushed potential problem sizes beyond the reach of most users. The dominant restrictions remain in code execution speed and robustness, which the developers constantly strive to improve. 
RELATED SOFTWARE:INGRID, GRIZ, NIKE3D, TOPAZ3D, and DIGLIB 
UNIQUE FEATURES:Contact slide surface Methods for automatic and Lagrange contact methods, Explicit integration, mass augmentation, rigid/deformable material switching and advance material constitutive behaviors. 
OTHER PROG/OPER SYS INFO:Fortran files use a .f extension, make files end in .mk, include files terminate with .h and all of the example problems are in the EXAMPLES subdirectory and begin with d3.

HARDWARE REQS:UNIX workstations and CRAY running Unicos. Memory requirement is problem-size dependent, however a minimum memory of 16 MB is recommended. 
TIME REQUIREMENTS:Execution time is problem size and simulation duration dependent. Thus short problems take 1 minute while the long ones can take several weeks.
