3 Outline ANSYS 14.0 Geometry Advances ANSYS 14.0 Meshing Advances 3

4 ANSYS 14.0 Geometry Advances 4

5 ANSYS 14.0 Geometry Advances Focus on enhancing your productivity through new features, increased flexibility, efficiency and usability ANSYS DesignModeler Core modeling improvements Application-specific modeling ANSYS SpaceClaim Direct Modeler Improved Workbench integration Enhanced Model Preparation Interoperability Support for new CAD releases New CAD file readers 5

6 Direct Entity Input for Modeling Operations Direct entity selections are accepted for Extrude, Revolve, Sweep and Skin/Loft operations Named selections and sketches remain supported as valid inputs for greater automation and flexibility 6 Extrude Revolve Sweep

7 Toolbar Customization Option to customize Toolbars based on physics or other modeling preference for easy and direct access to preferred features and tools All features and tools Mechanical centric features and tools Fluids centric features and tools Electronics centric features and tools 7

8 More Hot Keys New set of hot keys (short cuts) for frequently repeated operations F3: Apply F4: Cancel F6: Toggle display (shaded+edges/shaded/wireframe) F7: Zoom to Fit Ctrl-A: Select All Ctrl-P: Toggle Point selection filter Ctrl-E: Toggle Edge selection filter Ctrl-F: Toggle Face selection filter Ctrl-B: Toggle Body selection filter Sketching mode only Ctrl-Z: Undo Ctrl-Y: Redo Ctrl-C: Copy Ctrl-X: Cut Ctrl-V: Paste 8

9 Additional Visualization Controls Improved visualization controls for modeling and topology verifications Available through View options or directly from the Toolbar Edge Direction Display Vertex Display 9

10 Additional Usability Enhancements Single/Box selection toggle RMB + LMB combination to easily toggle between the two selection modes Auto Freeze during slicing Slice feature and Slice Material operations are now available for all bodies Both active and frozen Active bodies involved in the slice are changed to frozen state automatically 10 Active Bodies Bodies involved in the slice are changed to a frozen state automatically

11 Improved Named Selection Transfer and Error Handling Improved Named Selection transfer between ANSYS DesignModeler and other ANSYS Workbench applications Improved Error handling Attach failures Share topology failures A new export property inside DesignModeler to control named selection transfer to other workbench applications Improved error handling to provide appropriate error and warnings in case of failures 11

12 Mid Surfacing Improvements Selection tolerance Tolerance is used to detect face pairs in case of imperfect offsets Selecting an undetected pair manually provides feedback on tolerance value required, which can be used for automated selection Default value is set to zero Trimming and other cleanup improvements Selection tolerance value is suggested to user 12 Without selection tolerance All the pairs detected successfully with Selection tolerance

13 Rotor Shaft Feature A new option to import and create Shaft geometry Reads input from a text file and automatically creates line bodies with specified crosssections Line bodies for rotor shafts Cross sections are assigned automatically Input data in a text file 13

14 Improved Interoperability with Ansoft Products Bi-directional geometry transfer between Ansoft products and Workbench applications for multiphysics simulations (DesignModeler/Mechanical/Meshing) 14

15 Improved CAD Interoperability Several new readers to provide two types of interfaces for all major CAD systems for improved productivity and flexibility Associative Interfaces Associative, parametric and Bi-directional Readers Native file readers for users without live CAD access Pro/Engineer A new DWG Reader for AutoCAD Improved model processing for faster and targeted updates ANSYS DesignModeler 15

16 CAD Interoperability Options Geometry Interfaces at R Associative Interfaces (Associative, bidirectional and parametric) Creo Parametric Creo Elements/Pro Creo Elements/Direct Modeling NX 8.0 Inventor 2012 SolidWorks 2011 Solid Edge ST3 (103) Solid Edge ST4 CATIA V5 R21 Teamcenter , 8.3 CAD Readers AutoCAD 2012* Creo Elements/Pro NX 7.5 Inventor 2011 SolidWorks 2011 Catia V5 R20 Catia V4 IGES and STEP Parasolid 24.0 ACIS R20 GAMBIT 2.4 * Requires an AutoCAD installation

17 ANSYS SpaceClaim: Improved Integration Improved ANSYS Workbench Integration Improved Associativity and data transfer Support for multiple design points Preview options for Topology Sharing Preview sharing to view topology sharing before transferring the model into Workbench Help detect and fix topology sharing issues before transfer 17

18 ANSYS SpaceClaim: Improved Selection and Repair Improved Selection and Repair Options More Selection Options Select Parents Select Children ClipView option to isolate and examine selected region Multi-face patch option for fixing missing faces ClipView Without multi-face patch on With multi-face patch on 18

19 ANSYS 14.0 Meshing Advances 19

20 Rapid & Robust Meshing Top on the list of challenges engineering companies are facing is shortened product development schedules while at the same time the product designs themselves are becoming increasingly complex. Meshing of these designs introduce challenges in terms of speed, robustness and accuracy. Courtesy Siemens AG. 20

21 Selective Control Persistence Record and replay sequence of meshing steps Flexibility Adv. Front surface meshing Separate min size for curvature & proximity 21

22 Virtual Topologies Virtual Topologies (VT) enabling improved automation, flexibility, and usability: More interactive usage through direct graphics interaction rather than tree objects Ability to run Auto VT on selected edges, faces or bodies Clustering of faces/edges Create hard vertex Face splits Improved meshing performance w/vts Cluster 1 2 Virtual Faces created. 1 for each cluster. Cluster 2 22

23 Virtual Topologies Flexibility: Allows user to get mapped or swept mesh in easier fashion 23

24 Virtual Topologies 24

25 Mesh Connections Mesh connections now work at part level: Post mesh connections by default (pre option still exists) Base part mesh stored to allow for quick changes 25

26 Mesh Connections Local connection changes or mesh changes only affect local area: 26

27 Support for default and/or uniform quad/tri Can mix and match mesh methods with mesh connections, and or use selective meshing: Default quad/tri Uniform quad/tri Mesh connections 27

28 Shell Meshing Improvements Better quad smoothing: Improved laplacian smoothing More ruled mesh on rectangles, etc Default quad/tri 14.0 Default quad/tri Example has ribs attached that are hidden 28

29 Hex Meshing MultiZone improvements Imprinting Through bodies Through long stretches of connected side faces Support for Match control Robustness Speed Speed improvements for multi-body parts with swept blocks 29

30 SUMMARY Geometry Advances: Usability Analysis specific custom tools Interoperability Meshing Advances: Automatic and Robust Meshing Shell Meshing Hex Meshing ICEM CFD and TGrid 30
