Creating Nodes to Nodes Connection Mesh

This task shows how to mesh points to points analysis connections.

You can mesh the Points to Points Analysis Connection created in the Generative Structural Analysis workbench. This connection can only be created if you installed the Generative Assembly Structural Analysis (GAS) product.
Do not use parabolic elements.

Open the sample36.CATAnalysis document from the samples directory.

  1. Click Nodes to Nodes Connection Mesh in the Welding Meshing Methods toolbar.

    The Nodes to Nodes Connection Mesh dialog box appears.

    • Connection modeling:
      • Rigid : lets you create a rigid element that will connect two sets of nodes associated to points.
      • DOF: lets you connect only specific degrees of freedom between two sets of nodes associated to points.
    • Replace existing nodes to nodes connection meshes: allows you to select a points to points connection that has been already associated to a mesh part.

      You must activate this option before selecting the points to points connection.
      If not, a warning message informs you that the points to points connection has been already meshed.
    • Connection name: lets you select one or several point to point analysis connections.

      Do not use a connection in which a point is associated to several mesh nodes.
    • Tolerance: lets you specify the distance between the nodes to be connected.

      The value must be strictly positive.
    • Stop update if error occurs: lets you stop the Update all meshes process.
      If this option is deactivated, the update mesh process will be tolerant.
      If this option is activated and an error is detected, the update mesh process will be stopped.

  2. Select the connection you want to mesh in the specification tree.

    In this particular example, select the Points to Points Analysis Connection.1 object in the specification tree (under the Analysis Connections Manager.1 set).

    The Nodes to Nodes Connection Mesh dialog box is updated.

    You can select several points to points analysis connections.

  3. Set the desired parameters.

    In this particular example:

    1. Select Rigid as Connection modeling option.

    2. Enter 1mm as Tolerance value.

  4. Click Apply and then OK.

    The specification tree is updated and a Nodes to Nodes Connection Mesh.1 appears:
