5.2.20. Output options (3)¶
Value |
Explanation |
(D=0)
|
Options for tally output after every batch.
|
=-1
|
No output.
|
=0
|
Output only numerical data files.
|
=1
|
Output both numerical data and image (*.eps) files [1] .
|
=2
|
Output to different files. (file name = specified file name + batch number))
|
=3
|
Output transition of tally results and these statistical errors as a function of the history number (or batch number). These values are output into a file '*_StD' where '*' indicates the file name specified in the tally section. This function is available only for [t-track] and [t-point].
|
=4
|
Output to different files by independently summarizing each batch results (file name = specified file name \(+\) batch number). This option cannot be selected in the batch variance mode (istdev=1). This function is available only for [t-track] and [t-deposit].
|
Value |
Explanation |
(D=1)
|
Option for the energy unit in tally outputs for nuclei (ions). Previously, this parameter was named iMeVperU with a default value of 0 (MeV). From Version 3.36, the name has been changed and the default value has been switched to 1 (MeV/n) to ensure consistency with the unit settings in the [Source] section (which primarily uses MeV/n). Please note that with this change, the default unit for ion tally results will switch from MeV to MeV/n. Note that the name iMeVperU can still be used, but not recommended.
|
=0
|
Output in total kinetic energy (MeV).
|
=1
|
Output in kinetic energy per nucleon (MeV/n).
|
Value |
Explanation |
(D=1)
|
Options for the tallying timing when the tracking particle is in a field, which constantly changes the particle’s momentum, such as a magnetic, electromagnetic, or gravity field.
|
=0
|
Tally at reaction or surface cross (normal).
|
=1
|
Tally at each step of the transport.
|
Value |
Explanation |
(D=0)
|
Options for the output format of the [material] section.
|
=0
|
e.g., mat[12], 208Pb.33c.
|
=1
|
e.g., mat[12], Pb-208.33c.
|
=2
|
e.g., m12, 82208.33c (MCNP style).
|
Value |
Explanation |
(D=0)
|
Options for the output format of material density in [material].
|
=0
|
No conversion.
|
=1
|
Conversion into particle density.
|
=2
|
Conversion into mass ratio (%).
|
Value |
Explanation |
(D=0)
|
Options of nuclear data information.
|
=0
|
No display.
|
=1
|
Writing in input echo. [2]
|
When IMeVperN=1, the unit of nucleus energy is changed from [MeV] to [MeV/n] in outputs of [t-track], [t-cross], [t-point], [t-product], [t-time], [t-interact]. For example, in the case of [t-track] with unit = 2, quantities in units of [1/cm \(^2\) /MeV/source] are converted to those in [1/cm \(^2\) /(MeV/n)/source].
[t-track] uses deltm as the step length to describe particle trajectories in fields that continuouly change particles’ momenta, such as a magnetic field. To describe the trajectory curve more smoothly, adjust the setting of deltm.
