[ 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.

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

**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, :numref:`fig-cell-ex6` in :numref:`sec-cell-lattice` is generated by the input shown below.
