Tool Tips

* How can I quickly find the right window when I have several Xfmea/RCM++ projects open?
Users' preferences and needs for working environments vary, so Xfmea and RCM++ offer viewing options to help you customize the software so that it is most effective for you. Just as some users prefer a hierarchical FMEA structure while others prefer a worksheet view, some users may want to view multiple project windows simultaneously in a given configuration (side-by-side, over/under, overlapping, etc.) while others find it more convenient to view one project at a time in a maximized configuration. Either way, all open windows can be accessed quickly and easily.

By default, the Project Explorer and each Project window open as separate, undocked windows within the MDI (as shown next in the RCM++ interface).

You can navigate among these windows in four ways:

  • Click the desired window.
  • Select the desired window from the list of active windows in the Window menu.
  • Click the View Project Explorer button to bring the Project Explorer into focus and then double-click the desired project.
  • Press Ctrl+Tab to bring another window into focus; you can cycle through all open windows in this way.

If desired, you can maximize these windows; all windows in the database will then remain maximized unless and until the window is restored to a partial-screen configuration (i.e. the setting will be retained when the database is closed).

When the windows are maximized, you can navigate among them in three ways:

  • Select the desired window from the list of active windows in the Window menu.
  • Click the View Project Explorer button to bring the Project Explorer into focus and then double-click the desired project.
  • Press Ctrl+Tab to bring another window into focus; you can cycle through all open windows in this way.

You can also use the tabbed view by selecting Use Tabs from the Window menu. In this view, all windows will be maximized and a tab will be displayed below the MDI toolbar for each open window within the MDI.

You can navigate among the tabs in four ways:

  • Click the desired tab.
  • Select the desired tab from the list of active windows in the Window menu.
  • Click the View Project Explorer button to bring the Project Explorer into focus and then double-click the desired project.
  • Press Ctrl+Tab to bring another tab into focus; you can cycle through all tabs in this way.

* How can on-condition maintenance be modeled in BlockSim?
To specify that preventive maintenance (PM) will be performed only when triggered by detection of an impending failure during inspection (i.e. on-condition maintenance), the following steps are required:

  • Specify an inspection policy that dictates when the block will be inspected and includes either the P-F interval or the failure detection threshold value that describes the detectability of impending failure for the block.

  • Specify a preventive maintenance policy that allows PM to be performed on the block but ensures that the PM does not occur unless and until is triggered by the detection of impending failure during inspection. Some options for creating such a policy include specifying that PM will occur at one of the following times:

    • Upon maintenance of another group item in this case, leave the default of 0 for the block's Item Group #. A group number of 0 indicates that the block is not part of a group, so there are no other group items and the PM will therefore not occur independently.

    • Upon fixed time interval based on system age in this case, specify an interval larger than the simulation time to ensure that the PM does not occur independently.
