Computing Using a Batch

A finite element computation is a succession of data manipulation processes in which input data resulting from a previous process (or directly input by the user) is converted into output data ready to be used by a subsequent process. Such ready-to-use data is stored in program objects sets such as those appearing in the analysis features tree under Analysis Cases (Restraints, Loads, Masses, Solutions) objects sets. 

When data contained in such an objects set is ready for use in the subsequent finite element computation process, the object has been computed and can be analyzed. Thus, Computing an objects set consists in generating finite elements results for all objects and objects sets necessary to analyze the specified objects set.

This task shows how to update and compute a document using a batch.

Computing a document will enable the analysis of any object of Restraints, Loads and Masses type, without requiring the computation of a Solution.

 

 

On NT

1. Duplicate CATIA V5 environment shortcut (on the desktop). For this, right-click on the Installation icon and select the Copy option from the contextual menu. Then, select the Paste option from the contextual menu.

2. Rename the duplicated icon. For this, double-click on the icon, select the Rename option from the displayed contextual menu and then enter the new name. For example, CNextBatch.

You will now assign a new path to the batch data by modifying the target name. For this:

3. Right-click on the duplicated V5 environment shortcut and select the Properties option from the contextual menu.

4. In Target modifiable field, enter the new path.

5. Edit the CNextBatch file and at the end of the file, replace
start CNEXT.exe -env %GenericEnvName% 

with the following:
start CNEXT.exe -env %GenericEnvName% -batch -e CATAnalysisBatch

As a result, when you launch the batch, a panel appears in which you will enter:
the name of the model to be read (input)
the name of the model to be saved at the end of the computation
the name of the computation storage file
the name of the result storage file

 

 

On UNIX

1. Open a window.

2. Go to the following directory:

SGI
/home/data/DassaultSystemes/B07/irix-a/code/command

IBM
/home/data/DassaultSystemes/B07/aix-a/code/command

HP
/home/data/DassaultSystemes/B07/hpux-a/code/command

SUN
/home/data/DassaultSystemes/B07/solaris-a/code/command

3. Launch the command below:
catstart -direnv /CATEnv _run /bin/ksh
CNEXT -b -e CATAnalysisBatch
