User Interface, Menus 48 w � If the line includes torsion and the line end connection twist stiffness is zero, then the end gamma will be set to the gamma of the end node, as found by the static analysis. This action can be useful if you want to set the line end orientation to that which gives zero end moments when the line is in its static position. To do this first set the end connection stiffness values to zero, then run the static analysis and then click the Use Static Line End Orientations menu item. You can then set the end connection stiffness to their actual values. 3.5.4 Calculation Menu Single Statics Start the single statics calculation (see Static Analysis). Progress and any error messages that occur are reported in the Statics Progress Window, which is shown as a minimised window icon. The statics calculation can be interrupted by CLICKING the Reset button. Multiple Statics Starts the multiple offset statics calculation (see Multiple Statics). Progress and any error messages that occur are reported in the Statics Progress Window, which is shown as a minimised window icon. The statics calculation can be interrupted by CLICKING the Reset button. Run Dynamic Simulation Start a dynamic simulation (see Dynamic Analysis). If necessary, OrcaFlex will automatically do a statics calculation first. During the simulation, the Status Bar shows the current simulation time and an estimate of the time that the simulation will take, and all 3D View windows and Graphs are updated at regular intervals. Pause Dynamic Simulation Pause the simulation. To save the results of a part-run simulation you need to pause it first. The simulation can be restarted by CLICKING the Run button. Extend Dynamic Simulation This facility is only available when the current simulation is either paused or completed. It adds another stage to the current simulation, without having to reset. You are asked to specify the length of the new stage. You can then continue the simulation, without having to restart it from scratch. This is particularly useful if you have a simulation that has not been run for long enough. Note that data for the new stage, e.g. for winch control and vessel prescribed motion, are initially set to be the same as for the previous stage. However, the data for the new stage can be edited because the new stage has not yet started. Reset Reset the model, discarding any existing results. The model can then be edited or a new model loaded. View Warnings Displays a window allowing you to review all warnings displayed by OrcaFlex during a calculation (statics or dynamics). This feature is particularly useful for simulations run in batch mode or by Distributed OrcaFlex. In these circumstances warnings are not displayed since to do so would require user intervention. Line Setup Wizard Opens the Line Setup Wizard. The wizard is only available when the current simulation is in Reset state. Wave Scatter Conversion Opens the Wave Scatter Conversion form. This facility converts a scatter table of sea states to a scatter table of regular (i.e. individual) waves. Batch Processing Run a batch of analyses automatically while the program is unattended. See Batch Processing for details.
w 3.5.5 View Menu Change Graphics Mode Toggles the graphics mode between wire frame and shaded. Edit View Parameters Adjust the View Parameters for the active 3D View. Rotate Up / Down / Left / Right Change the view direction, for the active 3D View, by the view rotation increment. Plan Set the active 3D View to a plan view (Elevation = 90°). Elevation Set the active 3D view to an elevation view (Elevation = 0°). Rotate 90 / Rotate -90 Increase (or decrease) the view azimuth by 90°, for the active 3D view. Zoom In / Zoom Out Click the zoom button to zoom in (decrease view size) or SHIFT+CLICK it to zoom out (increase view size). Reset to Default View Set the view parameters for the active 3D View to be the default view of the model. Set as Default View Set the default view of the model to be the view parameters of the active 3D View. Show Entire Model Set the view parameters for the active 3D View so that the entire model will be displayed. Axes This submenu gives you control of the 3D View Axes Preferences. 3.5.6 Replay Menu Edit Replay Parameters 49 User Interface, Menus Adjust the Replay Parameters, such as the period of simulation to replay, the time interval between frames, the replay speed etc. For more information see Replays. Start / Stop Replay Starts or stops the replay. Step Replay Forwards, Step Replay Backwards Step the replay forwards or backwards one frame at a time. Click the button to step forwards; CLICK with SHIFT held down to step backwards. Replay Faster / Slower Increase or decrease the replay frame rate (replay speed). Export Video Exports the replay as a video clip in AVI file format. See Replays for more details.
