3. DESCRIPTION OF PROGRAM OR FUNCTION

MAZE is an interactive input generator for two-dimensional finite element codes. MAZE has three phases. In the first phase, lines and parts are defined. The first phase is terminated by the 'ASSM' or 'PASSM' command which merges all parts. In the second phase, boundary conditions may be specified, slidelines may be defined, parts may be merged to eliminate nodes along common interfaces, boundary nodes may be moved for graded zoning, the mesh may be smoothed, and load curves may be  defined. The second phase is terminated by the 'WBCD' command which  causes MAZE to write the output file as soon as the 'T' terminate command is typed. In the third phase, material properties may be defined. Commands that apply to the first phase may not be used in the second or third; likewise, commands that apply in the second may not be used in the first and third, or commands that apply in the third in the first and second. Nine commands - TV, Z, GSET, PLOTS, GRID, NOGRID, FRAME, NOFRAME, and RJET are available in all phases.  Comments may be added anywhere in the input stream by prefacing the  comment with 'C'. Any DYNA2D or NIKE2D material and equation-of- state model may be defined via the MAT and EOS commands respectively. Maze may be terminated after phase two; it is not necessary to define the materials.

8. RELATED AND AUXILIARY PROGRAMS

MAZE is specifically designed as a  preprocessor for the DYNA2D (NESC9910), TOPAZ2D (NESC 9801), and NIKE2D (NESC9923) nonlinear structural analysis programs, but it is  compatible with other finite element codes.
The LLNL-developed DIGLIB (NESC 9639) graphics software used with the DEC VAX and SUN version is included with those version.
