How to get results from the analyses

Extraction of results can be made in several ways, as follows:

  • Detailed results plots: Any results can be extracted from the simulation files (DSS files) upon completion of the analysis. Standard post-processing features include static and quasi-static analysis results, dynamic results, spectral results. The outputs shown in the simulation file include plots, numerical values, and statistics related to the curves.

  • Predefined results: Predefined results are results requests that can be defined before the analysis is run. Predefined results can be setup from the Predefined Results form associated with any analysis. These results are automatically processed on opening the simulation file (DSS file). Predefined results may apply to individual analyses (e.g. analyses listed in the Default analysis set) or to all analyses included in an Analysis Set. Processing of the predefined results requests can be made in batch mode with the Batch Processing tool. Predefined results requests may also serve to generate batch post-processing script files: right-click the Analysis or Analysis Set in the Model Browser and select the "Generate batch post-processing file" item in the pop-up menu.

  • Batch post-processing script files: Batch post-processing scripts are text-based files including post-processing instructions applicable to one or several analyses. These scripts files may be generated by the interface based on predefined results and further updated with any text-editor to match with your results requests. Extraction of results with post-processing script files must be made in batch mode with the Batch Processing tool.

  • Results statistics: Results statistics are reported within every simulation files (DSS files) along with detailed plots and numerical values. These statistics are displayed in the Statistics tab.

  • Global results statistics: Results statistics associated with series of analyses included in an Analysis Set may be grouped and exported in a single Excel file. Export of these global statistics can be made once post-processing of detailed results is complete. To this purpose, open the model file, right-click the name of the Analysis Set, and further select the Export Statistics item in the pop-up menu. This will create a single Excel file showing results statistics for the analyses included in the Analysis Set. Export of these global statistics can also be made in batch mode using the Batch Processing tool. To this purpose, open the Batch Processing dialog, select any model file (DSK file) as job file, and set the job type to Export to Excel. This will create a single Excel file listing all results statistics per Analysis Set. These Excel files are located in a folder named "export_dsk".

  • Zones Study results: The Zones Study post-processing feature allows to define several critical zones along a riser such as top section, sag/hog area and touch down point region, and to carry out automated post-processing along these zones for series of different analyses. All results produced by this automated post-processing feature are grouped into summary results tables showing for instance minimum and maximum values of selected results.

  • Clearance analysis: The clearance check feature enables post-processing the minimum clearance between several lines for series of static and dynamic analyses. Clearance check tasks are defined and handled through the Clearance Check form which may be opened from the Tools menu by selecting the Clearance Check item. The Clearance Check interface enables you setting up your clearances post-processing requests and display associated results in tabular forms.

  • Fatigue damage analysis: Model files may include the definition of one or several fatigue analyses. The various fatigue analyses attached with your model are located in the folder labelled "Fatigue" displayed in the Model browser. Fatigue analysis provides the damage resulting from combined environmental conditions at selected hot-spots along lines for steel risers (homogenous pipe), mooring lines, and bonded hoses (Trelline hose type).
