7.20. [ T-Gshow ] section

This tally produces graphical geometry output for regions bounded by xyz mesh. These outputs can be obtained without transport calculation using the option icntl=7 in the [parameters] section.

The option of output=10, gshow=5 for other tallies, is useful for lattice and tetrahedral geometry with very fine mesh.

Table 7.20.1 mesh

value	explanation
xyz	Mesh type. Only xyz mesh can be set. A mesh type subsection is required below this option.

Table 7.20.2 axis

value	explanation
xy, yz, xz	2-dimensional.

Table 7.20.3 file

value	explanation
file name	Define output file names. This is required by each setting of axis.

Table 7.20.4 output

value	explanation
1	Region boundary.
2	Region boundary + material color.
3	Region boundary + material name.
4	Region boundary + material color + material name.
5	Region boundary + region name.
6	Region boundary + material color + region name.
7	Region boundary + LAT number.
8	Region boundary + material color + LAT number.
9	No output.
10	Material color in pixel style.

Table 7.20.5 resol

value	explanation
1 (default)	This option multiplies the region line resolution by a factor of resol.

Table 7.20.6 width

value	explanation
0.5 (default)	The option defines the line thickness.

Table 7.20.7 title

value	explanation
(optional)	Title.

Table 7.20.8 angel

value	explanation
(optional)	ANGEL parameters.

Table 7.20.9 sangel

value	explanation
(optional)	Special format for ANGEL parameters.

Table 7.20.10 x-txt

value	explanation
(optional)	\(x\) axis title.

Table 7.20.11 y-txt

value	explanation
(optional)	\(y\) axis title.

Table 7.20.12 epsout

value	explanation
0 (default), 1, 2	When epsout=1, results are plotted into eps files. The eps file is named by replacing the extension with .eps. When epsout=2, error bars are also displayed in the eps file, except for the 2-dimensional type, axis=xy, yz, xz, rz.

Table 7.20.13 bmpout

value	explanation
0 (default), 1	Generate Bitmap figure of 2-dimensional tally output. This file is named by replacing the extension with .bmp. When mesh=xyz and axis=xy, yz, xz, it is available.

Table 7.20.14 vtkout

value	explanation
0 (default), 1	Output the tally results in the xyz mesh in the input format of ParaView. This file is named by replacing the extension with .vtk. When mesh=xyz and axis=xy, yz, xz, it is available.

Table 7.20.15 vtkfmt

value	explanation
0 (default), 1	Format of output file for ParaView. 0: ascii, 1: binary.

Table 7.20.16 trcl

value	explanation
(optional)	Coordinate transformation number or definition for r-z or xyz mesh.

Table 7.20.17 gslat

value	explanation
2 (default)	Option to draw lattice or tetrahedral geometry boundary lines when gshow or rshow is specified.
0	Not drawing.
1	Drawing. Note that the line of voxel phantoms may not be drawn clearly.
2	Not drawing the lines in the same cell.
3	Not drawing the lines in the same material. In this case, the boundary of two adjacent cells filled with the same material is not also drawn, even if not lattice or tetrahedral geometry. When gshow>=3, cell and lattice numbers are now shown.

output=7 and 8 can be used only when the cells in bottom level are themselves in the lattice; the output then gives lattice numbers in the format (4,1,2). For example, Fig. 5.6.11 in Section 5.6.4 is generated by the input shown below.
