CATIA allows the user to perform design optimisation in a short time using “ product engineering optimiser” inside the “knowledgeware” module. CATIA Knowledgeware. CATIA® V5R Formulas. Formulas are used to build relationships between parameters. They are the first type of relation that you will. Catia V5 knowledgeware awareness session. Francois Trudel.

CATIA Knowledgeware Infrastructure

Create a formula based on existing definitions or measurements in the model. The Formula Editor is displayed. U1 contains a value calculated using a formula; click the formula icon at the right of the text field to view or edit the formula.

It is possible to add values to a single value parameter after creating it. Measure between Set a parameter equal to the distance between two model entities. This association is performed using the quick formula.

To reorder parameters, right-click the parameter to be reordered, and select Reorder Creating a Design Table from a pre-existing File. After you specify a range, Nonlinear Structural Analysis or Thermal Analysis displays an error message if an entered value exceeds the limits.

If need datia, rename this parameter. Editing or modifying a parameter. However, only the value of the object is propagated to subsequent steps.

Applying Knowledgeware

The Reorder dialog box is displayed. In the formula rule or check editor, cxtia the Design Table item in the dictionary, the list of the methods that can be applied to a design table is displayed.


Enables you to reorder a relations set or a parameters set in an existing set. The import file must be either a.

It is possible to add ranges and cattia values to a design table. For example, if you create a displacement boundary condition in Step 1 and use a Knowledgeware formula to modify the value for Step 2, the resulting value will be propagated to Step 3.

Incorporating Knowledgeware into model and analysis parameters allows other users to work with the model more effectively. In the Formulas Editor, select the parameter that you have just created. There are several techniques that you can use to add Knowledgeware to analysis parameters.

Edit the material parameter from the specification tree, then enter the new material in the parameter editor. You can now reorder parameters sets and relations sets as you already could do for parameters and relations. Create 3 parameters of length knoowledgeware with the following values:.

Edit formula Create a formula based on existing definitions or measurements in the model. When the active configuration does not fit the set of configurations resulting from a query operation, you get a message prompting you to deactivate the filter uncheck the filter box or change your configuration.

If you try to delete a relations set containing hidden relations, a message is displayed asking you if you want to delete the relations set that contains hidden relations. Specify the file containing the design table data, then create the necessary associations. Displacement boundary conditions Temperature boundary conditions Pressure loads Point knowledgeeware Gravity loads Rotational body force loads Surface heat fluxes Point heat fluxes Film conditions Initial temperatures Temperature histories There are several techniques that you can use to add Knowledgeware to analysis parameters.


Creating a multiple-value knowledgewsre. Fulfill the function prototype and allow for the required number of arguments. Select the relations set that you want to reorder in the specification tree.

Select a method, then click F1 to display the associated documentation. Modifying the Part Number.

U3 has a range of acceptable values created using Add range ; there is no indication that this Knowledgeware technique is in use unless you caia a value that exceeds the allowable range.

If neither action is undertaken, your design table takes on a broken status.

Declaring a parameter as constant. To assign multiple values to a parameter, select Multiple values at parameter creation and enter the values one by one to specify the value list.

CreateSet “Name of the new set”.

Design Optimisation Using CATIA Knowledgeware Module

Specifying mnowledgeware measure in a formula. You can use the Dictionary list to view the commands for a specific data type or function. The distance between both edges is displayed in the Results pane. A parameters set or a relations set can only be reordered in the same document.
