Make mesh tally size settings for MCNP

Description

#' : Find the parameters needed for a rectilinear "superimposed mesh tally b" in MCNP. It can be a challenge to center mesh tally bins at a desired value of x, y, or z. This function looks at a single dimension, – in units of cm – at a time. This is a new function and hasn't been tested thoroughly. The idea is to identify a single setting in the MCNP mesh tally for imesh and iints (or jmesh and jints or kmesh and kints). It is designed only for uniform mesh bin sizes.

Usage

mcnp_mesh_bins(
  target,
  width,
  lowest_less,
  lowest_high,
  highest_high,
  highest_less
)

Arguments

target

the desired center a single mesh

width

the individual mesh

lowest_less

in the direction of a decreasing dimension, what is the lowest that it can go and still be acceptable?

lowest_high

in the direction of an increasing dimension, what is the lowest that it can go and still be acceptable?

highest_high

in the direction of an increasing dimension, what is the highest that it can go and still be acceptable?

highest_less

in the direction of a decreasing dimension, what is the highest that it can go and still be acceptable?

Value

a data frame providing:

low_set, the minimum dimension. This is probably best used in the origin parameter in the MCNP mesh tally. high_set, the maximum dimension for the bin. This can be identified in the MCNP mesh tally setting of imesh, jmesh, or kmesh. width, this is just a return of the parameter supplied to the function. numblocks, the number of fine meshes. This can be used in the MCNP mesh tally setting of iints, jints, or kints.
