Comparing Clash Command Results

You can compare clash command results with:

• A previous computation
  This comparison is based on numeric and/or graphic clash command results whenever these results are available. For a more pertinent comparison, select the Compute penetration depth or minimum distance option during the initial computation (Tools > Options..., Digital Mockup > DMU Space Analysis -> DMU Clash tab).

• Results stored in a PDM system (ENOVIA VPM or ENOVIA LCA).


For interoperability to work correctly, ensure that you have set up both your CATIA V5 and ENOVIA LCA or ENOVIA VPM sessions properly.

Before running your check, set the appropriate Retrieve Information option in the DMU Clash tab (Tools > Options..., Digital Mockup > DMU Space Analysis).

Additional information is provided in the Check Clash dialog box to help you analyze results.

Info Column (Retrieve Information from previous computation)

New:

The conflict is new.

Old:

A contact is detected and the previous conflict was also a contact.

Modified:

 

Three cases:

 

(1) The conflict already exists, but the interference type has changed. For example, a clearance is now detected whereas previously a clash was detected.

(2) Comparison of numeric and/or graphic clash command results indicate that the conflict is not the same as the previous conflict.

(3) No numeric and/or graphic clash command results are available.

If you do not select the Compute penetration depth or minimum distance option (Tools > Options..., Digital Mockup > DMU Space Analysis > DMU Clash tab), the list of conflicts is updated but no numeric result is available when you click Apply. This means that no comparison with a previous computation, if existing, is possible.
For a more precise result, select the Compute penetration depth or minimum distance option. However, note that this option may be costly and may adversely affect performance if a large number of conflicts are involved.

Note: All modified results are given the not inspected status.

Modified_old:

Comparison of numeric and/or graphic clash command results indicate that the conflict is identical to the previous conflict.

Note: You can filter results in this column.

Info Column (Retrieve Information from PDM)

New:

The conflict is new.

Old:

The conflict is identical to an existing conflict in the PDM system.

Modified:

The conflict already exists, but changes to product geometry were made in the PDM system after initial clash results were stored.
All modified results are given the not inspected status.

Modified_old:

The conflict already exists, but changes to product geometry do not impact stored clash results.

Note: You can filter results in this column.

Keep Column (Retrieve Information from PDM only)

This column lets you define which results you want to store in the PDM database.

No value:

No decision to keep or otherwise results has been made.

Keep:

Clash results will be stored in the PDM database when you exit the command (OK in the Check Clash dialog box).

No Keep:

Clash results will not be stored in the PDM database.

Cannot Keep:

Clash results cannot be stored in the PDM database. The geometry or position of at least one of the two conflicting products has changed. You must first save products in the PDM system before saving clash results.

Location Column (Retrieve Information from PDM only)

This column distinguishes between database and session conflicts.

Base:

The conflict in the session and the one stored in the PDM system are identical. There has been no change in product geometry or position of either of the two conflicting products. Nor has there been any change in conflict attributes  (status, comment, etc.).

Session:

The conflict in the session is different from the one stored in the PDM system: the geometry or position of one of the two conflicting products, or one of the conflict attribues (status, comment, etc.) has changed.

Note: These two values are managed by the system. You cannot modify them directly.
