Solid Edge Simulation From Plm World 2009

  1. 1. Solid Edge SimulationPLM World Presentation<br />July 1, 2009<br />Mark Burhop<br />Product Manager, Solid Edge Analysis Products<br />@burhopon Twitter<br />Mark Burhop on Facebook<br />
  2. 2. Content<br />Background<br />Existing Need<br />Target User<br />FEA Functionality<br />Brief description of Process<br />SE Simulation Functionality Review<br />Loads, Constraints, Studies, Mesh, Solving and Post Processing.<br />
  3. 3. CAE Products to Cover All Needs<br />Femap<br />Femap Express<br />Solid Edge Simulation<br />Analyst<br />GAP<br />Engineer<br /><ul><li>Native Solid Edge “in window” application
  4. 4. Separately purchased product</li></ul>CAD User<br />Single Part Validation<br />Assembly Validation<br />System Simulation<br />(Dynamic, CFD, Heat, multi-physics)<br />Problem Complexity <br />
  5. 5. Target is the Designer Analyst<br />Designer Analyst<br />Someone that splits time between Design and Analysis.<br />Does not do advanced analysis. It is either not needed by the customer or is covered by a dedicated analyst using FEMAP.<br />Often the “super designer” at small companies being asked to do more faster.<br />Desires<br />Easy of use.<br />Geometry only commands.<br />Extended help and guidance relative to “dedicated analysis” tools such as FEMAP.<br />Familiar interface.<br />Understandable results.<br />
  6. 6. Designer Products - Differences With Analysis Products<br />Geometry Focused – Designers will work only with Geometry (i.e. Force on face). You will need a high end product (FEMAP, NX Advanced Simulation,) to work directly with nodes and elements.<br />Single Solver – SE Simulation will use only NX Nastran. Femap supports multiple solvers.<br />Designer Language Rather than Analyst Language<br />Easy Geometry Modification Capability –Synchronous Technology has interesting potential for CAE model preparation.<br />More Process Oriented – UI organized to step you though a process. More help and suggestions to guide the designer when problems occur.<br />
  7. 7. Analysis Steps <br />Model Preparation and Simplification– Modify “designed” geometry to meet the needs of analysis.<br />Preprocessing – define the loads, constraints, material properties and connections between assembly parts. <br />Mesh – define the type of mesh to be used and refine it as needed. <br />Solve – The solve occurs when the FEA model composed of the mesh, loads, and constraints are passed to NX Nastran for analysis. <br />Post Processing – examine the results from NX Nastran using various visualization and reporting tools. <br />
  8. 8. Solid Edge Simulation<br />
  9. 9. A Quick Analysis<br />Demo<br />(At PLM World, a demo was given here)<br />
  10. 10. Environment<br /><ul><li>A new Tab and Ribbon bar in Part, Assembly, SM environments.
  11. 11. integrated into these environments
  12. 12. (turned on with License)
  13. 13. A Simulation navigator is provided for Studies
  14. 14. Can also be used as an alternative to the ribbon bar for command access.</li></li></ul><li>Environment Simulation Tab<br />Part – Analysis Tab<br />Assembly – Analysis Tab <br />
  15. 15. Study Navigator<br />Provides a tree view with drag and drop functionality for working (create, edit, delete, copy, etc...) with FEA Analyses/Studies, load sets, and constraint set results<br />It is important to note that an analysis study can be totally defined through the Study Navigator<br />With a RMB click the user can define geometry, loads, constraints, mesh, etc….<br />
  16. 16. Study Navigator <br />A Study can be created by RMB clicking on “Simulation” in the study Navigator<br />Once the Study is created the user can easilyrename, copy, delete, modify, solve, or usethe save to Femap .mod file <br />material can be added or changed<br />
  17. 17. Demo<br />Study Creation<br />(At PLM World, a demo was given here)<br />
  18. 18. Mechanical Loads<br /><ul><li>Covers the available geometry based FEMAP mechanical Loads.
  19. 19. Temperature load (for body only – thermal expansion)
  20. 20. Handles for defining direction, orientation.
  21. 21. Quick bar options for input.</li></li></ul><li>Constraints<br />The following types of constraints are supported<br />Fixed<br />Pinned<br />No rotation<br />Sliding Along Surface<br />Cylindrical<br />Valid entities to select are faces, edges, and points (vertex)<br />
  22. 22. Demo <br />(At PLM World, a demo was given here)<br />
  23. 23. Meshing<br />Support for 2D Mesh and 3D tetrahedral mesh.<br />UI options that change between environments (i.e. Sheet metal defaults to 2D mesh)<br />The “Mesh” commands can be executed from either the command bar or from the study Navigator.<br />command to set the mesh sizing for edges and faces.<br />
  24. 24. Demo<br />Mesh<br />Mesh Sizing<br />(At PLM World, a demo was given here)<br />
  25. 25. Solve Command<br />Command to run the analysis (execute NX Nastran)<br />UI to expose some NASTRAN options (GEOMCHECK)<br />Key piece of this will be handling NASTRAN errors in a user-friendly way. <br />Some UI for displaying actual NX Nastran errors for more advanced users.<br />
  26. 26. Post processing – plots and graphics <br />Colorized plots, contours<br />Displacement, animation, mode shapes.<br />Internal and External element display<br />Display of results in context of assembly, other graphics.<br />
  27. 27. Color Bar<br />Provide additional indicators for key material properties.<br />Provide color display options with overflow and underflow values.<br />Saving of color bar options across sessions.<br />Ability to position color bar at different locations and sizes on the screen.<br />Grayscale<br />Rainbow<br />Stoplight<br />

  36. 36. New “User Assistance”- combined Help and Self-paced Training<br />For the SE Simulation product, Education Media will implement several enhancements to the user learning experience:<br /><ul><li>Combined user help and self-paced training-asingle destination for customer learning. Single-source textual and graphic content reduces localization costs for Siemens PLM.
  37. 37. Workflow-based landing pages as anchors to keep new users focused on the order of doing something and providing a link from each step directly to a procedure.
