mcnp_est_nps | R Documentation |
Provides quick estimate of number of particles histories, (nps) to obtain target MCNP 'error'. Paste may include up to three tallies side by side in the default MCNP order. For example, the headers of a three tally report includes column names: nps, mean, error, vov, slope, fom, mean, error, vov, slope, fom, mean, error, vov, slope, fom. The structure of the tfc has been the same for versions 4 through 6, including MCNPX.
