Optimizing geometry to drive design By leveraging the powerful geometry engine within NX Advanced FEM, you have access to a large number of geometry parameters that can be used to drive opti- mization processes. Design variables can include feature and sketch dimensions and expressions as well as some FE parameters, such as section properties for one-dimen- sional elements and shell properties for two-dimensional elements. However, geometry optimization is not restricted to designs built in NX. You can import geome- try from other applications and define NX Advanced FEM seamlessly integrates with geometry design variables using synchro- Teamcenter simulation process management. nous technology. Capturing knowledge and automating processes NX Advanced FEM allows engineering organ- izations to capture the expertise of senior analysts and make it available for others in the organization to use in the form of wiz- ards or templates. CAE processes can be captured and automated using NX Open, an open framework for automation and programming. Analysts can capture the steps in a CAE process using journaling, and then develop scripts and easy-to-use dialog boxes so others can use the same Drive design through simulation-based geometry process.
