All rights reserved Siemens PLM Software Associativity for Imported Data 1.Create a new part 2.Import IGES/ProE/STEP data 3.Switch to Advanced Simulation and create and Idealized part, FEM and SIM. 4.Switch to the Idealized part.  Insert/Associated Copy/Wave Link  Select all bodies 5.In the FEM and SIM files, create the mesh, properties and boundary conditions. Solve the model. 6.SAVE ALL files. 7.Create a new part. 8.Import the revised geometry in the same format. Green lettering indicates the steps required to maintain associativity.

All rights reserved Siemens PLM Software Associativity for Imported Data 13.Switch to the FEM and update the Mesh.  If any modifications were done on the FE entity level, they will need to be repeated. 14.In the SIM, create a clone of the original solution. Solve the new model. Both results files are available to compare.

Page 6 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Create a New Part A new part must be created before importing data.

Page 7 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Importing Data Select the import file type desired. Fill out the required data on the form.

Page 8 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Create FEA Files Switch to the Advanced Simulation application. Create a new FEM and SIM. Make sure that “Create Idealized Part” option is checked. To make geometry selection easier, change the use bodies to ‘Select Bodies’ and do not select any bodies.

Page 9 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Create Wave Link Switch to the Idealized part. Create a wave link of the geometry.  All bodies can be selected.  Turn on the “Hide Original” option.

Page 10 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Create FEA Model If the “Select Bodies” option was chosen, you need to add geometry to the FEM. Highlight the FEM  Under the 3 rd Mouse button, select Edit Select all bodies.  Only the linked bodies should be displayed

Page 11 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Create FEA Model Create the required mesh in the FEM. Create the desired boundary conditions in the SIM.

Page 13 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Revised Part Create a new file and import the revised data.

Page 14 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Using the Revised Part Switch to the idealized part. Select the Assembly Navigator.  Highlight the part  Under 3 rd Mouse Button, select When prompted select the revised part. This part can be loaded into NX or can be selected from the O/S.

Page 15 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software JT Update For JT files, a new revised part does not need to be created. Replace the original JT file on the O/S with the revised JT.  Use the same name Make the part the displayed part. Select: File/Properties Select: Update Part File Switch to the idealized part.

Page 16 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Updating the Part Switch to the Part Navigator Highlight the Linked Body  Under the 3 rd Mouse Button select Edit Parameters  Select the new body. Select the Replacement Assistant
