Solid Edge Simulation - PLM Connection 2009

  1. 1. Mark Burhop Solid Edge Simulation PLM World Presentation July 1, 2009 Mark Burhop Product Manager, Solid Edge Analysis Products @burhop on Twitter Mark Burhop on Facebook
  2. 2. Mark Burhop 2 Content ►Background ► Existing Need ► Target User ►FEA Functionality ► Brief description of Process ►SE Simulation Functionality Review ► Loads, Constraints, Studies, Mesh, Solving and Post Processing.
  3. 3. Mark Burhop 3 GAP Solid Edge Simulation CAE Products to Cover All Needs Problem Complexity CADUserAnalyst Single Part Validation Assembly Validation System Simulation (Dynamic, CFD, Heat, multi-physics) Femap Express Femap Engineer Native Solid Edge “in window” application Separately purchased product
  4. 4. Mark Burhop 4 Target is the Designer Analyst ► Designer Analyst ► Someone that splits time between Design and Analysis. ► Does not do advanced analysis. It is either not needed by the customer or is covered by a dedicated analyst using FEMAP. ► Often the “super designer” at small companies being asked to do more faster. ► Desires ► Easy of use. ► Geometry only commands. ► Extended help and guidance relative to “dedicated analysis” tools such as FEMAP. ► Familiar interface. ► Understandable results.
  5. 5. Mark Burhop 5 Designer Products - Differences With Analysis Products ► 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. ► Single Solver – SE Simulation will use only NX Nastran. Femap supports multiple solvers. ► Designer Language Rather than Analyst Language ► Easy Geometry Modification Capability –Synchronous Technology has interesting potential for CAE model preparation. ► More Process Oriented – UI organized to step you though a process. More help and suggestions to guide the designer when problems occur.
  6. 6. Mark Burhop 6 Analysis Steps ► Model Preparation and Simplification– Modify “designed” geometry to meet the needs of analysis. ► Preprocessing – define the loads, constraints, material properties and connections between assembly parts. ► Mesh – define the type of mesh to be used and refine it as needed. ► Solve – The solve occurs when the FEA model composed of the mesh, loads, and constraints are passed to NX Nastran for analysis. ► Post Processing – examine the results from NX Nastran using various visualization and reporting tools.

  8. 8. Mark Burhop 8 A Quick Analysis Demo (At PLM World, a demo was given here)
  9. 9. Mark Burhop 9 Environment ►A new Tab and Ribbon bar in Part, Assembly, SM environments. ► integrated into these environments ► (turned on with License) ►A Simulation navigator is provided for Studies ► Can also be used as an alternative to the ribbon bar for command access.
  10. 10. Mark Burhop 10 Environment Simulation Tab ►Part – Analysis Tab ►Assembly – Analysis Tab
  11. 11. Mark Burhop 11 Study Navigator ►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 ►It is important to note that an analysis study can be totally defined through the Study Navigator ►With a RMB click the user can define geometry, loads, constraints, mesh, etc….
  12. 12. Mark Burhop 12 Study Navigator ►A Study can be created by RMB clicking on “Simulation” in the study Navigator ►Once the Study is created the user can easily rename, copy, delete, modify, solve, or use the save to Femap .mod file ►material can be added or changed
  13. 13. Mark Burhop 13 Demo ►Study Creation (At PLM World, a demo was given here)
  14. 14. Mark Burhop 14 Mechanical Loads ► Covers the available geometry based FEMAP mechanical Loads. ► Temperature load (for body only – thermal expansion) ► Handles for defining direction, orientation. ► Quick bar options for input.
  15. 15. Mark Burhop 15 Constraints ►The following types of constraints are supported ►Fixed ►Pinned ►No rotation ►Sliding Along Surface ►Cylindrical ►Valid entities to select are faces, edges, and points (vertex)
  16. 16. Mark Burhop 16 Demo (At PLM World, a demo was given here)
  17. 17. Mark Burhop 17 Meshing ► Support for 2D Mesh and 3D tetrahedral mesh. ► UI options that change between environments (i.e. Sheet metal defaults to 2D mesh) ► The “Mesh” commands can be executed from either the command bar or from the study Navigator. ► command to set the mesh sizing for edges and faces.
  18. 18. Mark Burhop 18 Demo ►Mesh ►Mesh Sizing (At PLM World, a demo was given here)
  19. 19. Mark Burhop 19 Solve Command ►Command to run the analysis (execute NX Nastran) ►UI to expose some NASTRAN options (GEOMCHECK) ►Key piece of this will be handling NASTRAN errors in a user-friendly way. ►Some UI for displaying actual NX Nastran errors for more advanced users.
  20. 20. Mark Burhop 20 Post processing – plots and graphics ►Colorized plots, contours ►Displacement, animation, mode shapes. ►Internal and External element display ►Display of results in context of assembly, other graphics.
  21. 21. Mark Burhop 21 Color Bar ► Provide additional indicators for key material properties. ► Provide color display options with overflow and underflow values. ► Saving of color bar options across sessions. ► Ability to position color bar at different locations and sizes on the screen. Grayscale Rainbow Stoplight
  22. 22. Mark Burhop 22 Probe ► Allow the user to probe specific node data. ► Creates a tool which can return information about nodes by moving the mouse cursor over the results and their data. ► Provide Min-max markers for key stress ► Provide table with copy/paste
  23. 23. Mark Burhop 23 Reports ►Create Report ►Similar to Femap Express ►HTML Output ►Remembers Settings!
  24. 24. Mark Burhop 24 Demo ►Post Processing ►Color Bar ►Probe (At PLM World, a demo was given here)
  25. 25. Mark Burhop 25 Assembly connectors ►Provide the linear and glued connectors that are supported by Femap and NX Nastran. ►Provide an automated tool to connect touching faces in an assembly. ►Provide a manual UI for selecting faces on assemblies that will be connected. Manual Connector
  26. 26. Mark Burhop 26 Demo ►Connectors (At PLM World, a demo was given here)
  27. 27. Mark Burhop 27 Solid Edge Simulation Assembly ►Covers certain special needs for Assemblies not addressed by other projects. ► Assembly level features from Traditional assemblies ► Traditional Weldments ► Assembly default Material Traditional Weldment brought into Synchronous assembly
  28. 28. Mark Burhop 28 Simulation Options ►A new “Simulation” tab has been added to the “Solid Edge Options” dialog to display various Solid Edge Simulation options ► Default NX NASTRAN options ► Default Meshing options ► Default Study options ► Default Plot options ► Default Load and Constraint options ► Number of Modes to return
  29. 29. Mark Burhop 29 Save to FEMAP ►Command to create a Femap .mod file from a Solid Edge Simulation Study. ► Transfers loads and constraints, mesh and results.
  30. 30. Mark Burhop New “User Assistance”- combined Help and Self-paced Training For the SE Simulation product, Education Media will implement several enhancements to the user learning experience: •Combined user help and self-paced training-a single destination for customer learning. Single-source textual and graphic content reduces localization costs for Siemens PLM. •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. •Focused SE Simulation help file: When the user is executing a Simulation command only SE Simulation “User Assistance” is active; removes the clutter of other SE help.
