Crunch
Crunch is a software utility that performs several types of post-processing analyses for one or more files.
Crunch includes scales and offsets, crosstalk elimination, peak finding, statistics, azimuth averaging, histogramming, and rainflow cycle counting. Much of the code for Crunch came from the GPP and GenStats programs. Crunch performs many of the same analyses as GPP, but it is more of a batch program, whereas GPP is an interactive program. If you are performing repetitive tasks, Crunch is the better choice.
Crunch was written to process wind-turbine test or simulation data, but it is probably useful for most tabular data.
This software was developed by Marshall Buhl of NREL.
Note: NREL is not furthering the development this software. The links below are provided for archival purposes only. The development of Crunch was replaced by development of the MATLAB®-based post-processors MCrunch, MLife, and MExtremes.
