Recomputation

AVEVA Clash Manager™ 14.3 User Guide

Clash Manager Configuration : Recomputation

Recomputation is an administrator configuration task that becomes necessary when the values of significant attributes in the 3D model have been changed, for example, if discipline codes are changed. This is because these changes to the 3D model are not automatically communicated back to the AVEVA Clash Manager, unless the relevant clash sets are rerun, or the recomputation process is initiated at these windows.

The changes to the 3D model can have been made independently in the base product, or in AVEVA Clash Manager at the AVEVA Clash Manager Configuration window. Following changes made in the base product, the recomputation windows must be accessed manually. When significant items are modified at the AVEVA Clash Manager Configuration window, the recomputation windows are displayed automatically with the appropriate default entries in the relevant options. Examples of the changes that cause automatic display of the window are:

•

rules added or deleted

•

regular expressions modified

•

defaults changed

•

defined attributes changed.

When the recomputation process is performed, it is usually necessary to preserve the current approval status, in spite of any change in Acceptance Rules that would subsequently lead to different results. Also, it should be noted that rules are applied only when a clash is initially discovered; subsequent manual settings of attributes usually need to be preserved. Clash acceptance can be excluded from the process, as can any other aspects, by appropriate entries at this window.

Evaluate Element Properties

From the AVEVA Clash Manager - Administrator window, select Evaluate Element Properties, the Evaluate Element Properties part of the AVEVA Clash Manager - Administrator window is displayed.

The Class, Priority, Areacode and Discipline check boxes represent the default values of project-defined fields that can be set at the AVEVA Clash Manager Configuration window. The fields are used for selecting attributes, the values of which are to be copied verbatim into the AVEVA Clash Manager database for reporting purposes and use for filtering and so on. The checkbox titles show the default values and/or those of the attribute(s) set by the user.

The check box titles are the default values of project-defined fields that can be set at the AVEVA Clash Manager Configuration window. The fields are used for selecting attributes, the values of which are to be copied verbatim into the AVEVA Clash Manager database for reporting purposes and use for filtering and so on. The check box titles show the default values and/or those of the attribute(s) set by the user.

•

When checked, the value of the particular attribute is unconditionally recomputed for every element

•

When unchecked, the attribute is not affected by the recompute process

•

Evaluate Unset Only - the value of the particular attribute is only evaluated for elements where the attribute is currently UNSET.

Evaluate Clash Properties

From the AVEVA Clash Manager - Administrator window, select Evaluate Clash Properties, the Evaluate Clash Properties part of the AVEVA Clash Manager - Administrator window is displayed.

Selecting a clash property enables recomputation of the associated property, when not selected the property is not affected by the recomputation process.


Group Ownership of Clash Detail	When selected, Clash Group Ownership is recomputed for every clash detail.
Clash Assignment (Discipline Owner)	When the ALL option is selected at the drop-down list, the discipline ownership is recomputed for every clash detail. When a discipline is selected, the ownership is recomputed for clash details for that discipline only.
Clash Acceptance (Clash Status)	When the ALL option is selected at the drop-down list, the clash acceptance status is recomputed for every clash detail. When a status is selected, the clash acceptance status is recomputed for clash details where the status is currently the one selected.
Clash group worst case Level/Type	When selected, the Clash Group worst case Level/Type is recomputed for every clash detail.
Clash Group Status from details	When selected, the status of each active clash group is reset to the value of the worst case status of any of its member clash details. This option is provided for cases where clash detail status has been set by hand and the group status consequently may be out-of-date.
Remove ‘User Modified’ Flag and Recompute Manually set items.	When selected, all Manual Flags are unset and, in future, all clashes are treated as though their details had been set automatically.

Note:

If any group status has been set by hand, and Apply Group changes to Clash Details on the AVEVA Clash Manager Options window has been set to False, the member details status will not necessarily match the group status. Therefore, recomputation using the 'Clash Group Status from details' option could change the Clash Group status to that of the worst case member clash detail.
