User Interface, Menus 3.5.7 Graph Menu Use Default Ranges Sets the graph axes to their original ranges Values Displays a spreadsheet containing the numerical values on which the graph is based. Spectral Density (only available for time history graphs) Opens a new spectral density graph. Empirical Cumulative Distribution (only available for time history graphs) Opens a new empirical cumulative distribution graph. Rainflow half-cycle Empirical Cumulative Distribution (only available for time history graphs) Opens a new rainflow half-cycle empirical cumulative distribution graph. Properties Opens the graph properties form (which can also be opened by double clicking the graph). 3.5.8 Results Menu Select Results 50 w Display the results form which allows you to choose from the currently available selection of graphs and results tables. Graphs such as Time Histories, XY Graphs and Range Graphs may be created before a simulation has been run, thus allowing you to watch the variables during a simulation. Fatigue Analysis Opens the Fatigue Analysis form. Modal Analysis Opens the Modal Analysis form. Report Vessel Response Opens the Vessel Response form. 3.5.9 Tools Menu Lock / Unlock Selected Object Locking an object prevents it from being accidentally dragged or connected using the mouse on 3D views, for example if you nudge the mouse slightly while trying to DOUBLE CLICK. Lock / Unlock Selected Object toggles the lock on the currently selected object. If the lock is on, it will be switched off. If the lock is off, then it will be switched on. Locked Objects may still have their positions edited in the data Edit Forms. The status of the object locks is shown by symbols in the Model Browser. Lock / Unlock All Objects Locks or unlocks all objects in the model. Set Thread Count Allows you to change the number of execution threads used by OrcaFlex for parallel processing. Calculate Speed Index The Speed Index is an approximate measure of how quickly a machine can perform OrcaFlex simulations. Larger values correspond to faster machines. The Speed Index is also reported by Distributed OrcaFlex. The Speed Index is calculated by performing a series of floating point calculations that are representative of the calculations performed by OrcaFlex itself. The value reported is meant only to give an estimate of the relative performance of similar machines. It is always preferable, if possible, to compare actual OrcaFlex simulation run times for models representative of your typical use.
w Preferences 51 User Interface, Menus Allows you to control various program settings so that you can customise the program to the way you prefer to work. See Preferences. 3.5.10 Workspace Menu Open Workspace Opens a previously saved workspace file and restores the window layout described in that workspace file. Save Workspace Save the current window layout to a workspace file. Preserve axes ranges If this option is checked then graph axes ranges will be written to the workspace file. When the workspace is subsequently opened, those axes ranges will be restored. If this option is not checked then graph axes ranges are not written to the workspace file. When the workspace is subsequently opened, default axes ranges are chosen based on the extent of the curves shown in the graph. Make default for this file, Make default for this folder Makes the current window layout the default workspace for the current simulation file or for the current folder, respectively. The default workspace for a simulation file will be restored whenever you open that file. The default workspace for a folder will be restored whenever you open any simulation file in that folder. If a default workspace exists for a both a file and the folder containing the file, then the default for the file is used. Use file default, Use folder default Applies the default workspace to the current model. This is useful if you have changed the window layout and wish to restore the default workspace layout without re-loading the model. Remove file default, Remove folder default Deletes the default workspace. Most Recent Files List of the most recently saved workspaces in the directory which contains the current model. Selecting an item on the list causes the workspace to be loaded. 3.5.11 Window Menu Add 3D View Add another 3D View Window. Having multiple views on screen allows you to watch different parts of the system simultaneously, or to see different views at the same time (for example a plan and an elevation). Tile Vertical, Tile Horizontal Arranges all the windows (3D View, graph or spreadsheet) so that they fill the main window area and fit side by side without overlapping. The program automatically tiles windows every time a new window is created or deleted. Switch to Model Browser This command, and the corresponding command on the model browser's Window menu, enable you to switch focus between the main form and the model browser window. Statics Progress Displays the Statics Progress Window. External Function Output Displays a window containing the diagnostics text produced by external functions. Window List This is a list of all currently open windows. If a window is hidden under others it can be selected easily from this list.
