5.2. [ Parameters ] section

The various parameters of PHITS can be defined in [Parameters] using the following format:

[ Parameters ]

para1 = number | file.name

para2 = number | file.name

……….

The order of parameters can be changed. As each parameter has a default value, undefined parameters use the default values.

Parameters and default values are listed in the tables shown below. (D= ) indicates the default value.

• 5.2.1. Calculation mode
