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.

If you later knowledgewzre the value in Step 1, Step 2 and Step 3 will both have this new value and the formula that you used in Step 2 will be lost.

CreateSet “Name of the new set”. Add multiple values Specify a list of values that can be selected for a parameter. For more information on propagation, see Propagation. If need be, rename this parameter.

Applying Knowledgeware

You just have to keep on pressing the Ctrl key when you select parameters. Edit the parameter, then in the edition box, right-click the value field and select Change step In the Relation body, select the parameter to be modified and change its value. The new parameter is added to the parameter list. Click OK when done. It is possible to add values to a single value parameter after creating it. Edit the parameter, then in the edition box, right-click the value field and select Add Range 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.

The Formula Editor is displayed. Click the icon located next to the parameter value field. Clicking this button displays the editor of the relation which constrains the parameter the formula editor or the rule editor for example.


If a parameter is already constrained, it does not appear in the Parameters to insert list in the design table dialog box. Specify the file containing the design table data, then create the necessary associations. Before doing this, check that the material catalog is installed on your machine. Incorporating Knowledgeware into model and analysis parameters allows other users to work with the model more effectively.

Only parameters which are not already constrained by any other relation or by any other design table can be used to create a design table. If you specify x in the Filter Name field of the Select parameters to insert dialog box, you will display knoqledgeware the parameters with the letter x in their name xA, xB, xC, xD, xE.

Lock Lock the current value for a text field.

Design Optimisation Using CATIA Knowledgeware Module

It is possible to valuate a boolean with a predicate instead of using operators. You must unlock the field to edit the value. Displacement boundary conditions Temperature boundary conditions Pressure loads Point loads Gravity loads Rotational body force loads Surface heat fluxes Point heat fluxes Film conditions Initial temperatures Temperature histories There are cwtia techniques that you can use to add Knowledgeware to analysis parameters.

Enables you to reorder a relations set or a parameters set below an existing set.

Relations Parameters Formulas Design Tables. Note that this indicator is not recursive. Change the part number in the Edit name or value of the current parameter field.

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

Using the dimensions of a sketch in a formula. Click the icon in the Knowledge tool knowledheware. In the Reorder window, select In or After and select a relation. In the formula rule or check editor, select the Design Table item in the dictionary, the list of the methods that can be applied to a design table is displayed. Modifying the Part Number. Add range Specify mnowledgeware for a parameter and indicate whether the limit values are included or excluded from the acceptable range. Tips about the access functions to the design table.

You can use the Dictionary list to view the commands for a specific data type or function.

A parameters set or a relations set can only be reordered in the same document. When you click a formula in the specification tree, then click the Formulas icon, the parameter list displays the constrained parameter, the formula activity and the parameters used as input in the formula. A file selection dialog box is displayed. Double-click the parameter in the specification tree. This part is intended for those of you who need a quick answer to their questions about the Knowledgeware capabilities.

Second Method Click the icon in the Knowledge tool bar. Adding Ranges and Values to a Design Table.

Objects are not gathered by types any longer. To add a column to a design table, open the. The following Nonlinear Structural Analysis and Thermal Analysis boundary conditions, loads, and fields support the use of Knowledgeware:.

You can now rearrange the columns without deassociating the parameters and the columns and associating them again just afterwards. The Filter Name and Filter Type filters can be used to restrict the display of a parameter list. If you do this, the group of multiselected parameters will be carried forward onto the Inserted parameters list in the order in which they are displayed in the initial list.
