CATIA V5 Knowledgeware

Knowledgeware is a group of techniques that you can use to control parameters based on your knowledge of the model and its intended application. Incorporating Knowledgeware into model and analysis parameters allows other users to work with the model more effectively. The following Nonlinear Structural Analysis and Thermal Analysis boundary conditions, loads, and fields support the use of Knowledgeware:. There are several techniques that you can use to add Knowledgeware to analysis parameters. The Knowledgeware options allow you to create formulas based on interdependent model values, specify a range or a list of acceptable values, and lock the current value of a parameter. You can also add a comment to a parameter to indicate the reason for the Knowledgeware control. Create a formula based on existing definitions or measurements in the model.
