3.9. Card 8: Nuclide yield file specifications

Table 3.9.1 INMTCF PHITS: same name

Value	Description
(D=1, INMTCF\(\leq\)10)	Number of nuclide yield files. If using [T-Dchain] to generate this input deck, this option should be automatically set to 1.
\(>\) 1	Files listed in HHNMTCF repeated with FFNMTCF for INMTCF times
= 1	Single yield file whose name is provided to HHNMTCF.
= 0	No yield file (used for standalone calculations without PHITS)

Table 3.9.2 FFNMTCF PHITS: not settable

Value	Description
	Normalization factor for regionwise nuclide yield file(s). If INMTCF\(>\)1, this entry and HHNMTCF must be repeated INMTCF times. Input decks generated by [T-Dchain] should have this automatically commented out.

Table 3.9.3 HHNMTCF PHITS: not settable

Value	Description
	File name (string) of the nuclide yield file.

Table 3.9.4 ITDCHOUT PHITS: not settable

Value	Description
(D=0, DP=1)	Flag indicating if nuclide yield output is from [T-Dchain].
= 0	Yield file is coming from a legacy source / using a legacy format.
= 1	Yield file was produced by the PHITS [T-Dchain] tally.

Table 3.9.5 IERTDCHO PHITS: same name

Value	Description
(D=0, DP=1, requires IDCHOUT=1)	Flag specifying if statistical uncertainties from the [T-Dchain] tally’s nuclide yield (*.dyld) and neutron flux spectra (*.dtrk) outputs should be propagated to the final results. Note that this changes the formatting of the *.act output file with newly added columns for uncertainty and error bars added to the ANGEL plots.
= 0	No uncertainty reading/propagation.
= 1	Yield and neutron flux statistical uncertainties are read from their files and propagated through the DCHAIN calculations.

Table 3.9.6 HENMTCF PHITS: not settable

Value	Description
	File name (string) of the nuclide yield uncertainty file. This can only be provided if ITDCHOUT=1. If ITDCHOUT is not 1, please remove or comment out this entry; otherwise, DCHAIN will halt its calculation to alert the user that this mismatch has occurred. (Only actually used when IERTDCHO=1 and IREDUFMT=0; ignored otherwise.)

Card 8b: Nuclide yield and neutron flux file special options

Table 3.9.7 IREDUFMT PHITS: same name

Value	Description
(D=0, DP=1)	Flag which tells DCHAIN if it is receiving neutron flux and yield output from [T-Dchain] in the original full or new reduced format.
= 0	Files use original full T-Track axis = eng and T-Yield formats.
= 1	Files use new reduced T-Track axis = dchain / T-Yield formats.

Table 3.9.8 IRDONCE PHITS: same name

Value	Description
(D=0, DP=1)	Controls if flux and yield files are reopened in each region.
= 0	Files are closed, reopened, and reread in each region.
= 1	Files only opened and read once unless HNFLUXS changes between regions or, for yield files, if IREDUFMT=0, speeding up simulations.
