  2. 2. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Agenda Connector Training•  Introduction •  What are Connectors? Why to use them? How do they work?•  New connector panel structure •  Where to create the connectors? •  Final connection routines for •  Spots / Seams •  Bolts•  Live demonstrations •  Connector Browser •  Part Replacement (reconnect rules) •  Spot, Seam, Bolt Mesh Imprint and resolve conflicts •  Seam Partitioning •  et. al
  3. 3. Connectors - What are they?•  They are geometric entities (not FE) primarily used to create spot- and seamwelds, but also used to create adhesives, bolts and masses.•  They are simply a database of information defining specific requests for connections at specific locations.•  They are a medium to create both solver independent and/or solver dependent connections between geometric and/or FE entities.•  They can be created interactively or from different master connection files (.xml, .mcf, .vip).
  4. 4. Connectors - Why to use them?•  Connectors hold definition of: •  connection locations (spots, seams, adhesives, bolts) •  linked entities •  re-connect rules •  et al.•  Connectors manage realized FE type and entities like •  rigids, CWELDs, MAT100s, hexa adhesives, et al.•  Allows switching between different FE weld types•  Allow quick part reconnection •  replacement by names or IDs
  5. 5. Connector – How do they work? Initual situation: Link Entity Entity Type: Comp Entity ID: 1 Entity Name: “top” Connector Location Entity Type: Point Entity ID: 10 Link Entity Entity Type: Comp Entity ID: 2 Entity Name: “bottom”
  6. 6. Connector – How do they work? Connector Definition: Link Entity Entity Type: Comp Entity ID: 1 Entity Name: “top” Unrealized Connector (yellow) Entity Type: Connector Entity ID: 7 Link entities: Comp 1, Comp 2 Thickness: 2 Link Entity Entity Type: Comp Entity ID: 2 Entity Name: “bottom”

Connector Realization: Link Entity Entity Type: Comp Entity ID: 1 Entity Name: “top” Realized Connector (green) Entity Type: Connector Entity ID: 7 Link entities: Comp 1, Comp 2 Thickness: 2 FE Config: 70 (acm detached) FE Tolerance: 5.0 (enough for projection) Connector created weld element Entity Types: Elements (Hex8, RBE3) Link Entity Entity Type: Comp Entity ID: 2 Entity Name: “bottom”
  10. 10. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Connector – How do they work?•  There are tree different connector states •  Yellow unrealized connector •  new created or imported connector before the first realization •  editing the connector definition (i.e. add or delete a link entity from the connector), the connector removes the welds it created, and reverts back to an unrealized state. •  manual unrealization •  Green successful realized connector •  Red failed connector •  If the creation of the FE representation is unsuccessful (due to low tolerance, insufficient link entities, etc.) the connector icon is displayed as failed (red).
  11. 11. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Connector – How do they work?•  Separating the FE representation from the connector definition comes with a lot of advantages •  Connector can easily be re-realized as a weld of a different configuration without redefining it. •  If you edit the connector definition (i.e. add or delete a link entity from the connector), the connector removes the welds it created, and reverts back to an unrealized state. •  If the creation of the FE representation is unsuccessful (due to low tolerance, insufficient link entities, etc.) the connector icon is displayed as failed (red).•  An unrealized connector is yellow, a realized connector is green, and a failed connector is red.
  12. 12. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Connectors - Where to create them?•  Spot, Bolt, Seam, Area Panels •  Main connector panels •  They are subdivided in at least three subpanels, which behave very similar: 1.  subpanel for a combined connector creation and realization 2.  subpanel for a pure connector creation 3.  subpanel for a (re)-realization of already existing connectors •  Whereas the edit or the partition subpanels are different or belong exclusively to a certain connector type the tree listed subpanels look and behave very similar. Three columns can be identified. Here marked with colored boxes.
  13. 13. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Connectors - Where to create them?•  The blue column contains everything related to •  connector creation •  and link detection.•  In this column are defined: •  location •  link candidates •  number of layers •  tolerance•  Dependent on the connector type (spot, bolt, seam, area) and the selected locations additional options are provided.
  14. 14. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Connectors - Where to create them?•  The orange column contains everything related to •  realization type •  post script or •  property assignment•  In this column are defined: •  realization type specific definitions like certain dimensions or number of elements, etc. •  which property the FE representation should get or if a certain property script should be used to manage those property assignments
  15. 15. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Connectors - Where to create them?•  The yellow column contains everything related to •  the final connection to the link entities.•  There are different routines which describe in more detail how the connection between the FE representation and the link elements should be achieved. •  The routines differ depending on the connector type; similar methods are offered for spots, seams and area connectors, but bolt connectors need completely different methods.
  16. 16. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Final connection routines for Spots, Seams and (Areas)•  The connection routines are clearly 1. 2. 3. 4. structured. mesh independent•  Not all realization types are allowed mesh quad to be used with all routines. dependent adjust mesh transition imprint•  Mesh independent has to be used for skip imprint realization types, where the final remesh connection is realized per solver definition. adjust find nearest realizations nodes project and find nodes ensure projection

  19. 19. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Examples for Seams – Adjust realization•  Connector fails, if testpoints use the same nearest nodes for the element creation. Therefore a larger spacing maybe senseful.
  20. 20. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Examples for Seams – Adjust mesh •  Note, that remesh with quadseams does not lead necessarily to clear t- edges.
  21. 21. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Final connection routines for Bolts•  The connection routines are clearly 1. 2. 3. 4. structured. mesh independent•  Not all realization types are allowed consider mesh to be used with all routines. dependent existing holes only•  For all mesh independent bolt realization types a cylinder is defined. create hole, if non adjust hole position (2D) realize & hole detect No bolt hole detection is performed, use hole, adjust details . . if available realization because no holes are required. All nodes inside the cylinder are fill & remesh hole, considered to be part of the bolt if available realization.

  53. 53. Copyright © 2012 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.Conflicting imprints – 1st strategyResolve conflicting imprints•  Smaller conflicts can be resolved automatically when realizing the connectors. This releases the overlapping elements and performs a normal remesh in that area. This is permitted as long as the overlapping area is smaller than half the regular quad transition element. However, if a conflict is too great it cannot be resolved in this fashion.
