Batch Processing Interference Analysis

This section deals with clashes batch processing when working with both CATIA (V4 and V5) and  ENOVIAVPM

CATITF Batch ProgramTop

This batch program requires a CATIA V4 session. This session can be built through CATIA or the VPM session maker. The session contains the assembly (or the part of the assembly) on which the clash calculation is performed.

You need a specific input file (named FT05) to run your CATITF batch process, a typical FT05 file looks like this:

*PROJECT
*GROUP
*USER
*PASSWORD
*READ ZCATITF
*SESSION
CATITF-MMS-2001-04-26.14.12.1
*WRITE ZCATITF
*REPLACE NO
*CLEARANCE *DISTANCE 20
*ACCURACY 0.2
*GR1
*mdl0
*GR2
*mdl1
*mdl2
*RUN

How does CATITF communicate clash calculation results to ENOVIAVPM ?

Specific declaration variables are necessary to establish communication between the batch and  ENOVIAVPM

Example:

catia.INTERFER_OPTION_VPM : LOGICAL ;
catia.INTERFER_OPTION_VPM = TRUE ;
/* For the new clash detection software */
catia.INTERFER_NEW_DETECT : LOGICAL ;
catia.INTERFER_NEW_DETECT = TRUE ;
/* Creation of ccv instead of non-integrated PLL */
catia.INTERFER_CREATE_CCV : LOGICAL ;
catia.INTERFER_CREATE_CCV = TRUE ;
/* For option -i */
alias Z0058=CATIA.SESSION = '$HOME/db' ;
alias Z0059=CATIA.SESSION = '$HOME/dbwri' ;
alias EDIT01=catia.REPORT = '$HOME/g20/CATITF';

How does it work?

You ran the batch execution.At the end of the batch execution:
 

  • the batch looks for a VPM session.

  • If one is found, the batch communicates the clash calculation results to the VPM session via XCO

  • The results are then saved in the VPM session.

ITFCHECK Batch ProgramTop

To access ITFCHECK in ENOVIAVPM the following declaration parameters are required (here on V4 models):

CATCDMA.METHOD_LIST(x).CATAB = 'CATIA_MODEL';
CATCDMA.METHOD_LIST(x).TYPE = 'Reserved';
CATCDMA.METHOD_LIST(x).COMMAND = 'ITFCHECK';
CATCDMA.METHOD_LIST(x).WHERE = 'PSN';
CATCDMA.METHOD_LIST(x).ROLE = 'Tools';
CATCDMA.METHOD_LIST(x).TAG = 'CdmaPrincPanelOpenITFCHECK';

where "x" must be replaced by the appropriate value higher than the last value in your declaration parameter.

ITFCHECK can be declared in the tables DOCxxx and CATIA_MODEL. Adding this declaration parameter enables the display of the following window (from the PSN):

This allows you to enter the current parameters of ITFCHECK and to launch it if required.

More than one selection can be made in this window before clicking on OK. Not until you select the OK button are the FT05s generated.

Two tables (per environment) are available in ENOVIAVPM. They are structured as follows:

  • The CLASH table is managed just like a standard CDMA table via a profile, except
    columns INSTANCE_1_COMPID and  INSTANCE_2_COMPID are mandatory.

  • For ORACLE, this feature can only be implemented on databases for which catcdm.raw_coid=TRUE.

Accessing Clash Results in  ENOVIAVPMTop

In the PSN, an icon enables you to access the Interferences Management dialog box.
You can perform queries to find in the PSN those instances implicated in the interferences, to modify comments, etc.

Interactive Interference Analysis (CATIA V5/ ENOVIAVPM)Top

You can search for interferences interactively in CATIA and to save them in in  ENOVIAVPM.
You can also load CATIA V4 models and/or CATIA V5 documents into the DMU Navigator from in ENOVIAVPM.

To access this functionality on V4 models, add the following declaration variables:

CATCDMA.METHOD_LIST(x).CATAB = 'CATIA_MODEL';
CATCDMA.METHOD_LIST(x).TYPE = 'Reserved';
CATCDMA.METHOD_LIST(x).COMMAND = 'CATIAV5';
CATCDMA.METHOD_LIST(x).WHERE = 'PSN';
CATCDMA.METHOD_LIST(x).ROLE = 'Tools';
CATCDMA.METHOD_LIST(x).TAG = 'CdmaPrincPanelOpenCATIAV5';
Where x should be replaced by the value immediately superior to the value of the last declared method.

Before launching the interference calculation, make sure CATIA V5 can communicate the results to VPM. For this:
In Tools > Options > Digital Mockup > DMU Space Analysis > DMU Clash...  select Retrieve information from VPM option button.

  1. Load your product in CATIA V5

  2. Switch to the DMU Space Analysis workbench (Start > Digital Mockup > DMU Space Analysis)

  3. Click Clash in DMU Space Analysis toolbar,
    to search for interferences
