Code Manual for CONTAIN 2.0 - Federation of American Scientists

CELL, must follow the global input. One such section exists for each cell in the problem. Each
section has blocks of information required by the various physical models used in individual cells.
Finally, the file is terminated by the keyword EOF.

Figure 14-1. CONTAIN Input File Structure
Global and cell level input sections are shown in summary format the next level of detail in Figures
14-2 and 14-3, respectively. Each keyword and parameter will be explained in detail below.
Parentheses ( ), square brackets [], the symbol &&, and curly brackets{ } have special meanings
which will also be explained below. The purpose of the figures is to illustrate the overall pattern of
the global and cell sections of input.
As shown in Figure 14-2, the first blocks of information required in the global input group specify
control information, materials, and fission products. The data in these blocks enable the code to
allocate the total amount of global data storage space required. Thus, the first two blocks of data in
the global input must be the CONTROL and MATERIAL blockr, in that order. In the MATERL4L
block, the keyword MATERIAL should be followed immediately by the COMPOUND sub-block
and then by the USERDEF, FP-NAMES, or AERNAMES sub-blocks, if used.
The subsequent data consists of global blocks of data. These may occur in any order (provided they
precede the cell level input). In Figure 14-2, each left-justified keyword with the exception of EOI
