TMESH tally type data

Overview

MCNP6 offers two mesh tallies. The TMESH tally was developed for MCNPX, and FMESH for MCNP5. These are very similar and both were kept when merging MCNP5 and MCNPX into MCNP6.

For whatever reason, the TMESH data are also written to the MCTAL file. These are also known in user manuals as “Superimposed Mesh Tally Type A”.

Supported types

For reference, below are the supported types:

Type	Description
1	Track-Averaged Mesh Tally
2	Source Mesh Tally
3	Energy Deposition Mesh Tally
4	DXTRAN Mesh Tally
