Managing Links in a Finite Element Model Representation

Finite element model representations can link to entities including 3D shapes (support for meshes, support for groups...), other finite element model representations (in the assembly context), or Knowledgeware formulas.

When you modify the linked entity, you must synchronize or reconnect the finite element model representation.

About Finite Element Model Representations

When a linked entity is modified, the finite element model representation is not synchronized automatically. For example, if you modify the length of a pad that is meshed, the mesh is still valid but it is no longer synchronized with the geometry.

You can synchronize links:

When you remove or replace geometry that is a support for a finite element model specification (by deleting or replacing the 3D shape that contains the meshed geometry or by deleting the product that contains the meshed geometry), the finite element model specification is no longer valid. The Edit Links and Relations command or the Impact command allows you to easily identify the broken links in Mesh Creation and reconnect the links between geometric supports and finite element model specifications.

To replace the geometry and reconnect the links with the finite element model:

  1. Replace the geometry.
  2. Click Impact to analyze the broken links.
  3. Click Manual Reconnection , and select the new geometry.

    To learn more, see About Reconnecting Mechanism.

  4. To synchronize the links between the geometry and the finite element model specifications, click Synchronize Link in the Edit Links and Relations command or the Impact command.

    To learn more, see Synchronizing Links or Relations Using the Synchronization Assistant.

    The dialog box corresponding to the invalid finite element model specification appears. If several finite element model specifications are invalidated, the dialog boxes appear in sequence. Only the OK button is available.

    Important: You can change the support for a mesh specification only if this support has been deleted.
