5.2.1. Calculation mode¶
Value |
Explanation |
(D=0)
|
Basic control option.
|
=0
|
Normal PHITS calculation.
|
=1
|
Output cross section and kerma factor (please see /phits/sample/icntl1 in detail).
|
=3
|
Output only input echo for checking memory usage, libraries, and file links.
|
=5
|
Calculation assuming all regions are void (no reaction, no ionization) for geometry check, and volume and area calculations.
|
=6
|
Source check. Source positions can be tallied by [t-product].
|
=7
|
Execute [t-gshow] for graphical output.
|
=8
|
Geometry output of xyz mesh tally with gshow option for graphical output.
|
=9
|
Execute [t-rshow] for graphical output.
|
=10
|
Geometry output of reg mesh tally with rshow option for graphical output.
|
=11
|
Execute [t-3dshow] for graphical output.
|
=12
|
Re-calculate using dumpall file. Dumpall file is specified by file(15).
|
=13
|
Use of function to sum up tally results (Sumtally function).
|
=14
|
Use of automatic calculation of region volume.
|
=15
|
Execute [t-wwbg] to obtain [ww bias] parameters.
|
=16
|
Use of script of analysis function.
|
=17
|
Execute [anatally] to obtain results of analysis function.
|
Cross sections and kerma factors used in the PHITS simulation can be outputted by icntl=1. Please see “/phits/sample/icntl1” in more details.
By setting icntl=12, PHITS reads the previous event-by-event calculation result from a dumpall file created when the dumpall=1 option was activated. All of the transport events are reproduced by the dumpall file without being re-calculated again. Thus, maxcas and maxbch cannot be changed. This functionality is suitable for tallying different physics quantanties with the same simulation setup, especially when such a simulation setup is computational time consuming. However, it should be noted that calculation with dumpall=1 may create a huge dumpall file. Please refer to Section 5.2.26 for more details.
By setting icntl=13, two (or more) tally results can be summed: see Section 6.8 for further detail.
By setting icntl=14 with [t-volume], automatic calculations to obtain volumes of specified cells can be performed. See Section 7.18 in more detail.
By setting icntl=15 with [t-wwbg], automatic calculations to obtain parameters of [ww bias] can be performed. See Section 7.17 for further detail.
When use of script of analysis function, icntl=16 should be set in a PHITS input file.
