ANA_KEFF Output in V2.1.13

Post by MartinMagill » Fri May 24, 2013 6:39 pm

Hi all,

In my output files (i.e. [name]_res.m) using version 2.1.13, I'm finding that the ANA_KEFF variable is written with 6 components (rather than the usual 2). The first two components look like the usual output (ANA_KEFF estimate and corresponding SD).

In version 1.1.[16-19] and 2.0.0 this variable is written with 2 components, and in all versions I've used (including 2.1.13) all other KEFF estimators are written with 2 components.

This doesn't seem like it would affect anything for most users. I only happened to notice it because of how I have my testing scripts set up.

The estimator is calculated separately for delayed neutrons. The first two values are total, 3-4 are prompt neutron multiplication only and 5-6 delayed neutron multiplication only.
