Model

What is termed the Model is the group of model components in the model browser under the folder labelled Model. The model is part of the .DSK project file, and consists in various components such as risers, mooring lines, floaters, rigid bodies, buoys, waves, currents, winds, etc.

All these model components may be displayed in the 3D view window provided that :

  • The individual items are ticked in the Model Browser.

  • The control bar selecting the objects within the 3D view is set to 'All', or the items are included in the Analysis selected in this menu:

Creating new objects: You may build the model by selecting a new component from the Tool bar or from the Model item in the menu bar. Some components can be positioned directly in the 3D view window, as follows:

  1. Click the button corresponding to a new object in the Tool bar or select the new model component from the Model menu.

  2. Move the mouse over the 3D View window to approximately place the new model component where you want it to display. Crossed dotted lines indicate the position at which the object will be dropped when clicking the left mouse button.

Note

Model components (such as buoys, rigid bodies, or subsea arches) must be positioned in the horizontal plane prior to specify the vertical position. Positioning the model component in the 3D View window must then be done in two steps: the first click will determine the position in the horizontal plane whereas the second one will determine the vertical position.

Note

Model components such as waves, wind, current, imposed motion and imposed loadings cannot be positioned in the 3D View window by moving the mouse. The data form related to these components opens straight when clicking the associated model component button in the tools bar.

Note

You may abort creating the new model component by pressing the ESC key.

Moving an object: Any object may be easily moved by using the mouse in the 3D view window. To do so, click the Displace in XY plane or Displace in Z direction button placed in the tool bar.

Place the mouse cursor over the object (or connection point for lines) you want to displace, then hold the left mouse button pressed while moving the mouse over the 3D View window. Alternatively, the object's position may be exactly set up by specifying the coordinates from the object characteristics pane.

Removing an object from the model: Any object may be removed from the model by right-clicking the object's name from the model browser and then selecting the Delete option. Another convenient way to remove one or several objects at the same time is to use the Delete several objects button placed in the tool bar:

Alternatively, selecting and clicking an object in the 3D view window and pressing the Delete key will present a warning 'delete \<object>?' which you can accept.

Editing object properties : each object is characterized by a number of properties. You may access these by double-clicking the object as the mouse cursor is placed over the object in the 3D View window. It may be necessary to zoom in to complex models to ensure you are selecting the correct item. Alternatively, you may double-click the object's name from the model browser.

Note

Each object will change colour (or a bounding-box will appear) when the mouse pointer is hovered over it - this indicates it can be selected, but it must then be clicked with the mouse to validate the selection. In the conventional way, multiple items may be selected by holding down the Shift key while clicking successive objects.
