The Home tab is shown in the figure below.

Home Tab

Home Tab

This tab contains the standard Windows clipboard and editing commands, navigation commands, analysis run commands, along with vessel motions and display options.

The first three commands of the tab are contained in the Clipboard group and provide standard Paste, Cut and Copy operations for components. If necessary, PipeLay will automatically rename copied components to avoid duplication of component names. In this case, a message stating a component has been renamed will be displayed in the Status Area. Note that components can be copied within the same project or between different projects.

Four commands make up the Edit group. The Undo and Redo commands enable you to reverse or restore the previous action that you performed. The Rename command allows you to change the name of the component that is currently selected in the Project Sidebar. To change the name of the component, simply select the Rename command then type in the new name and press Enter to confirm it. The Delete command removes the component that is currently selected in the Project Sidebar from the project.

The Previous Component and Next Component commands are contained in the Navigate group and allow you to switch back and forward between components that you may be accessing regularly. This feature is very useful when used in conjunction with the fast navigation features discussed in the ‘Fast Navigation’ article. The Previous Component command takes you back through the components that you have previously viewed, starting with the most recent. Subsequently, selecting the Next Component command moves you forward through the component view history until you arrive once again at the most recently viewed component. Depending on how many components you have accessed since your launched PipeLay, either or both of these options may be greyed out or unavailable. For example, both commands are unavailable immediately after you launch PipeLay.

In the Analysis group the Run command starts an analysis. While an analysis is running, the Run command is unavailable and Stop command is available. If you select Stop, the analysis terminates completely.

The Run Postprocessing command runs the standard PipeLay postprocessing, including any custom postprocessing you’ve specified.

The Run Summary Postprocessing command runs summary postprocessing as requested on the Analysis component.

The Run Code Checking command initiates either DNV or API postprocessing as defined on the relevant tab of the Analysis component. This command is not available in PipeLay Starter Edition.

The Run Time History command allows you to generate a time history of vessel motion. This allows you to quickly identify periods of maximum vessel response, and subsequently perform dynamic analyses corresponding to these periods.

The Run Fatigue Analysis command performs a fatigue analysis based on the current Analysis component. This command is not available in PipeLay Starter Edition.

The Run Tabular Report command allows you to generate customised tabular output files. This option is of limited applicability to the majority of program users and is also not available in PipeLay Starter Edition.

The Plot RAOs and RAO Checking Module commands are contained in the Vessel Motion group. These commands are only available if a Vessel Motion component is currently selected. When you select the Plot RAOs command, PipeLay generates plots of the vessel Response Amplitude Operators (RAOs) specified in the selected Vessel Motion component and presents them to you. This allows you to visually inspect the RAOs for correctness. When you select the RAO Checking Module command, PipeLay runs the RAO Checking Module, which is a graphical tool that enables you to validate RAOs quickly.

Four buttons are present in the Additional group and are detailed as follows; the Views button allows you to adjust the PipeLay display. You can select or deselect to display the Sidebar view, Status area, Analysis Queue and the Help view. In addition, you can select the display theme from a wide variety of options. This will change the overall look of the program.

The Options button invokes the Options dialog, as shown in the figure below.

Options Dialog

Options Dialog

The Options dialog enables you to select some display options as follows:

Bitmap Background

When no component is selected in the Project Sidebar, PipeLay fills the Component View area with a patterned background. Very occasionally this may cause problems with older video drivers running under Windows 9x/ME. If you experience system instability while running PipeLay, it is recommended that you turn this option off by disabling Bitmap Background.

Coloured Data Buttons

When an input dialog contains data, the title text alters to a contrasting colour, to indicate that data has been stored. If you wish to disable the colour change, then you may clear the Coloured Data Buttons check box, and the title text will be simply underlined.

Arrange Folders Alphabetically

By default, PipeLay does not list the folders in the Project Sidebar in alphabetical order. If you select this option, PipeLay lists the folders and their contents in alphabetical order.

Enable Undo

If this option is unchecked, the Undo button on the Home tab will no longer function.

Enable Auto Recover

If PipeLay has to close unexpectedly and there were unsaved changes to a project file, the next time the project file is opened, PipeLay will ask the user if they wish to recover unsaved changes. If this option is unchecked, the auto recover feature will be disabled.

Concurrent Analysis Runs

When running multiple analyses at the same time or running an analysis where the stages are to be run in parallel, PipeLay will run analyses/stages concurrently up to the maximum number specified here. Any additional analyses/stages will be queued and started as soon as an analysis/stage finishes. The default number of concurrent analyses will be the number of licensed processors (as specified in your license file). This allows for the most efficient means of running multiple analyses/stages.

The Help drop-down provides access to the PipeLay help by selecting one of the following options:

Launch External Help - this launches the PipeLay help in non-embedded mode.

Launch Help Website - this opens the online hosted PipeLay help in a web browser

The Examples drop-down enables quick access to the PipeLay examples.
