Flexcom > Data Inputs > $LIFETIME CYCLE

Purpose

To specify data relating to histogram output.

Theory

Refer to Cycle Counting Analysis (Mode 2) for further information on this feature.

Keyword Format

One line with three values, two of which are optional:

No. of Channels in Timetrace File, [Start Time] [, Scale Factor]

Start Time defaults to the timetrace output start time. Scale Factor defaults to 1.

Table Input

Input:	Description
Number of Channels:	The number of individual data values output by Flexcom to the timetrace output files at each solution time. See Note (a).
Start Time:	The time (in seconds) at which to start using data from the seastate files. It is used to exclude initial transients from the cycle counting calculations. Any data from solution times prior to this start time is ignored.
Scale Factor:	This value is used to transform data in the Flexcom units to appropriate units for the histogram output. The value specified here is applied to all output channels. This input is optional, and defaults to 1.

Notes

(a)The Number of Channels must be the same for all of the files listed in the Seastate File – Specify table. Likewise, for meaningful cycle counting, the individual channels must be the same in each of the files. Note however that there is no requirement that the simulation lengths are the same in all of the analyses. Nor is it necessary that the individual solution times be the same in all of the Flexcom analyses.
