Data Collation |

You typically indicate to Flexcom which DBS files are to be included in the summary collation process, by specifying a master or “root level” directory in which Flexcom is to search for relevant files. Specification of the master directory is optional, and if omitted, it defaults to the current working directory (i.e. the folder in which the Summary Postprocessing Collation keyword file is located). You may also optionally invoke a Subfolders option, to indicate that you wish to include all subdirectories of the master folder (with the exception of hidden directories, system directories and symbolic links) in the search process also.
You may also a specific “tag” (or list of such tags) to be identified in the DBS file name, in order to refine the search. If you invoke this option, Flexcom searches through the DBS files, retaining only those which contain the specified tag in their file names. In order for a DBS file to be considered, its file name must contain all the specified tags. For example, this would allow you to easily sort “near” current load cases from “far” cases.
Assuming that at least two suitable DBS files are successfully identified, the collation process begins. You have control over what parameters you wish to collate, based on the descriptive titles assigned to various outputs during the creation of the Summary Output File for each individual analysis. This entry is optional however, and if you do not specify any descriptive titles for collation purposes, Flexcom will attempt to collate all available data. Only parameters which share the same descriptive title are compared (any outputs with blank titles are ignored).
You may also specify exclusion criteria to be applied, in terms of threshold levels for minima, maxima or standard deviation. If you choose to specify a threshold minimum, then any analysis where the parameter under consideration is less than the threshold is omitted. Likewise, if you opt to specify a threshold maximum or standard deviation, then any individual analysis results where the relevant parameter exceeds the threshold level is omitted. An output must pass all specified filters before it is included in the collated results.
•*IDENTIFY is used to identify output files for inclusion in summary postprocessing collation.
•*COLLATE is used to specify the summary postprocessing data to be collated and any exclusion criteria. This keyword is optional, and if you do not explicitly designate certain parameters for collation purposes, Flexcom will attempt to collate all available data.
If you would like to see an example of how these keywords are used in practice, refer to J03 - Summary Collation.
