Page 6 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Automatic Solid Geometry Preparation Geometry and Meshing Considerations  Analysts inherit CAD models that often contain difficult geometry  Serviceable for CAD, but cause problems with FE meshing  Affects mesh and element quality and hence solution accuracy  Typical problems include:  Sliver surfaces  Short edges  Narrow regions  Close points  Internal voids  Difficult geometry has to be fixed before the model can be meshed  Manual geometry clean up requires much effort and time The solution: Femap’s automatic geometry preparation capability  Greatly reduces and in many cases completely eliminates the need for manual combination, suppression and splitting of geometry

Page 7 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Automatic Solid Geometry Preparation  Automatic clean up allows:  Easier meshing of complex 3D models with problematic geometry  Easy removal of unnecessary detail  Geometry cleanup actions performed automatically include:  Combination of surfaces and curves  Suppression of small curves and surfaces  Surface splitting at strategic locations  User defined tolerance controls extent of geometry changes

Page 8 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Automatic Solid Geometry Preparation  Prepare Geometry and Mesh sizing tolerances  Guide geometry feature removal / suppression and mesh sizing  Internal voids identified and removed  Access to further geometry preparation and mesh sizing options

Page 9 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Automatic Solid Geometry Preparation  Full control over the extent of model simplification  Identify a group of entities that should be ignored  Entities that are loaded or constrained are ignored  Set maximum sizes and angles based on geometry preparation tolerance  Identify individual options to be included in the cleanup process

Page 10 © Siemens Product Lifecycle Management Software Inc. All rights reserved Siemens PLM Software Automatic Solid Geometry Preparation Benefits  Significant time savings with finite element model creation  Ease of use  Solid FE models are much easier to create and mesh first time  Combine with the interactive Meshing Toolbox to further tune and enhance the mesh Serial vs. Interactive Workflows
