Two utility programs are provided to further post-process the Zencrack results, in addition to the direct post-processing of detailed integration results and crack profiles described here:
The "process" utility program allows generation of a csv (comma separated variable) file containing detailed information for one or more positions on a crack front. This allows easy importing of data into a spreadsheet where the results can be plotted and analysed. This type of processing is essential in order to understand the large amount of data that can be generated in an analysis. Information can be extracted at:
Examples of these three methods are shown here:
A Microsoft Excel template is supplied to allow plots to be quickly generated from the csv file. The template is intended for use with a crack growth analysis but can readily be modified for other applications (e.g. single f.e. steps with multiple sets of results through a time history).
When using the template with results from a crack growth analysis, graphs are automatically available for:
The "3dmesh" utility program is an alternative to import of results into the Zencrack GUI and allows the crack growth history to be represented by a f.e. mesh that can then be viewed in a pre-processor. For example:
The output from 3dmesh may also be superimposed on the uncracked mesh to allow visualisation of the profiles against the specimen geometry. For example:
