Model browser

The model browser is a tree-view window that displays in the left part of the GUI. This window presents all the model components. Each component may be edited by double-clicking its name in the model browser. The model browser also features component management facilities, available through customized pop-up menus that display with a right click on the component's or folder's name.

The model browser content is split into six parts, as follows :

  • QA : the Quality Assurance Information window for your model.

  • Types : the list of types that may be used in a model, including : line types (i.e. mechanical properties that will be assigned to the lines in your model), Floater motion types (i.e. motion characteristics that will apply to the floaters), Contact types (properties used to model contact interactions between lines and other model components like lines, rigid bodies or Sea & Ground), buoyancy modules types, internal fluids, internal contents variation, external fluids, ballast properties, and the drag/lift database.

  • Model : the list of all model components that compose your model (for example, lines, floaters, rigid bodies, buoys, waves, currents...).

  • Analysis Sets : the list and definition of all standard type analyses included in the model.

  • Fatigue : the list and definition of all fatigue analyses included in the model.

  • Zones Studies : the Zones Study post-processing requests lists series of post-processing instructions that aim at getting results statistics for a range of analyses all grouped in the same results table.

  • BOP Studies : the list of all BOP studies included in the model.

  • Hull dynamic pressure : the list of Hull dynamic pressures studies.

  • Structural code check : the list of all Code Check studies defined in the model.

QA Data

The QA Information may be displayed by double clicking this icon. You can then modify the contents of the window provided that the file opened is a .DSK model file. The icon also displays when opening a .DSS simulation results file, but the QA data cannot be modified anymore.

Types folder

This folder lists all the different Line segment types, contact types and buoyancy modules types used in your model.

New types can be added to the model by right clicking the Line Types label (or Contact Types etc.) and then selecting which kind of new type you want to create from the pop-up menu. Once the new type is created, you can edit the corresponding properties by double clicking its name.

Model folder

This folder contains all the objects in your model. These objects may be added to the model using either the toolbar or the Model item from the menu bar. These objects are displayed in the 3D view window, unless you un-tick the box placed on the left side of the object's name.

Analysis Sets folder

This folder contains the definition of the different analyses associated with the model. The analyses are grouped into analyses sets. You may create a new set of analyses by right-clicking the Analysis Sets label, and selecting New Analysis Set from the pop-up menu. You may also create a single analysis by selecting New Analysis from that menu. Any analysis or analysis set may also easily be removed from the model by selecting Remove some analysis from that menu.

Right-clicking any individual analysis from the Model browser will display the pop-up menu shown below.

Using this pop-up menu, you may either :

  • Run analysis: Access the interactive mode for launching your analysis (see more details).

  • Check global weight breakdown: Run the global weight breakdown computation.

  • Delete: This deletes the analysis.

  • Rename: This renames the analysis. This command is also available by pressing "F2" with your keyboard once you have clicked on the analysis.

  • Copy: This duplicates the analysis. Name of the new analysis is set automatically with the extension "_1" so as to avoid 2 analyses having similar names.

  • Open DSS file: This opens the Simulation results file (.DSS) associated with the selected analysis. The file will open in the GUI only if it was previously created,

  • Generate DSS and LOG files: This generates the Simulation result file (.DSS) and Analysis input file (.LOG) associated with the selected analysis,

  • Generate DSS file: This generates the Simulation result file (.DSS) associated with the selected analysis,

  • Generate a batch post-processing file: This generates a batch post-processing instructions file associated with the Predefined Results requests of the selected analysis. This post-processing instructions file can then be run in batch mode with the GUI.

  • Edit calculation parameters: This edits the calculation parameters associated with the selected analysis.

  • Edit pre-defined results: This edits the pre-defined results requests associated with the selected analysis.

  • Export results statistics: This export to Excel results statistics for all results data included in the DSS file associated with the selected analysis. Statistics that are reported in the Excel file include minimum, maximum and mean values for all results data sets.

    Note

    This command can be invoked once the analysis and post-processing tasks are complete.
    The complete sets of statistics (e.g. including Std. deviation, skewness, kurtosis, time at maximum value, time at minimum value) are not displayed there for clarity. These statistics can however be viewed in the DSS file.
    Export of global statistics for a range of analyses included in an Analysis Set is also possible.

  • Edit: This edits the selected analysis, which allows you to select which components will be included in your analysis (see more details).

  • Check links between components: This reports whether all model components included in the analysis are properly linked together. A warning message would display if not the case (e.g. if a line is connected to a floater and the floater was not included in the analysis).

Fatigue analyses folder

This folder contains the definition of the fatigue analyses to be carried out on homogeneous pipes or mooring legs.

Zones Study folder

This folder contains the definition of all zones study automated post- processing requests attached with the model. These zones study post-processing requests allow to produce tabulated results for multiple analyses at one go. Requested results variables are displayed in tabs for several zones along the lines. These zones study post-processing requests are mainly intended for extreme and fatigue dynamic analysis of unbounded flexible risers.

Hull dynamic pressures

This folder contains the definition of the Hull dynamic pressures analyses.

Structural Code Check

This folder contains the definition of the Structural Code Check studies.

Search item

A search in all model items can be performed by clicking on the combo box on top of the tree view and by selecting the "Search" item.

Enter the item name and click on the "Search" button to locate the item in the tree view. Press the escape key to quit the search mode.
