This page deals with Analysis options.

Analysis Mode Activation

Ask permission to activate analysis mode
 When you select this option, the Analysis Mode Activation dialog appears whenever all of the conditions below are true:
  • You are modifying the analysis configuration
  • Analysis Mode is off
  • The modifications require Analysis Mode to be turned on.

DThe default value for this option is enabled.

Auto-Activate Analysis Mode
This option is available only when the Ask permission... option is not checked. If the Auto-Activate Analysis Mode option is checked, the Analysis Mode is turned on automatically when the analysis configuration has changed and the changes need the Analysis Mode On. If this option is not checked, the Analysis Mode is not automatically changed.

DThe default is that this option is not selected.

Display Analysis Status Window
When this check box is selected, the Analysis Status dialog box appears when the Analysis Mode On/Off command is set to On.  The Analysis Status dialog box consists of types of analysis objects.  When an Analysis Type is set to Inactive, it does not appear on the Analysis Status dialog box.  Users can override defaults set in the Tools > Options tab by using the Customize button on the Analysis Status dialog box.  However, once a session has been started, users cannot alter what appears in the Analysis Status dialog box by altering the options in the Tools > Options tab.  Any such changes take effect in the subsequent session.

DThe default is that this check box is not selected and that all the Analysis Types are set to Active.

Analysis Level

Allows the user to specify the default value to be used in the corresponding field from the Analysis Configuration dialog. Changes users make to the Analysis Level within the Analysis Configuration dialog box only persist for the session in which they occur; the default value is set in  Tools>Options.

Possible values: Off, Highlight, Verbose, Interrupt.

DThe default value for this option is Off.

Visualization Mode

Allows the user to specify the default value to be used in the corresponding field from the Analysis Configuration dialog. If the user changes the visualization mode through the Analysis Configuration command, this new value is then used, until there is another change in the Tools>Options.

Possible values: Highlight, Curves.

DThe initial setting is Highlight.

Analysis Feedback

Selecting Beep means that you will get aural feedback as well as visual feedback when you have a clash analysis enabled during the simulation.

D The default value for this option is disabled.

Static Analysis

Static analysis refers to analysis defined in the Analysis Configuration command and used during the simulation.

To use voxelization in static analysis, you must first activate voxelization in the Tools>Options>Digital Mockup>DMU Navigator tab.  For more information, see information about Fast Clash Detection.

Selecting the Use Voxelization check box means that static clash detection uses voxel-based, not geometry-based, static clash detection. Geometric clash uses the actual geometry when calculating whether an object is in clash with another object. Depending on the complexity of the objects, this can be time-consuming. Also, the bounding boxes of the objects are used to determine whether they need to be checked against each other at all.

Voxel clash uses a 3D grid of boxes which contain the objects to calculate whether an object is in clash with another object. Based on the user-defined voxel size, the grid of boxes is calculated such that both of the objects are completely contained within the grid. The clash detection is done by checking whether any of the boxes containing the first object clash with any of the boxes containing the second object. This clash detection is much faster for complex geometry because only boxes are checked against other boxes. On the other hand, the boxes may extend beyond the actual geometry for the objects, which may cause the voxel to report a clash even though the geometry does not actually clash.

The performance improvement for voxel clash is highly data-dependent and also highly dependent on the size of the voxel set by the user.

D The default value for this option is disabled (i.e., geometry-based static clash detection).
