Creating Line Analysis Connections

This task shows you how to create a line analysis connection.
Line analysis connections are used for simulating welding seam onto parallel faces, on an assembly model.
  • Only available with the Generative Assembly Structural Analysis (GAS) product .
  • The connection has to connect two bodies (2D or 3D).
  • Multi-selection is not available.

Open the sample48.CATAnalysis from the samples directory.

  1. Click Line Analysis Connection in the Analysis Supports toolbar.

    The Line Analysis Connection dialog box appears.

    • Name:  lets you change the name of the connection.
    • First component: lets you select the first "side" of the part that will support the connection.

      You can select one body (2D or 3D) or one mesh part.
      • Select Mesh Parts: this button is available only if a support is selected.
        For more details, refer to Selecting Mesh Parts.
    • Second component: lets you select the second "side" of the part that will support the connection.

      You can select one body (2D or 3D) or one mesh part.
      • Select Mesh Parts: this button is available only if a support is selected.
        For more details, refer to Selecting Mesh Parts.
    • Lines: lets you select the welding line.
      • Multi-selection is not available.
      • The line can be:
        • a border of the geometry
        • feature (line, curve).
    • Guide line on each component: lets you select a second line to guide the connection orientation.

      The projection of the welding line on guide line is possible if:

      • The guide line is face to face with the welding line.
      • The length of the guide line is equivalent to the length of the welding line.
      • The welding line and the guide line features are equivalent (that means that if the welding line is a curve feature, the guide line must be a curve feature).

  2. Select the first component.

    In this particular example, select Part6(Part6.1) - Fill.1.

  3. Activate the Second component field.

    To do this, select the Second component edit box as shown below:

  4. Select the second component.

    In this particular example, select Part5(Part5.1) - Extrude.1.

  5. Activate the Lines field.

    To do this, select the Lines edit box as shown below:

  6. Select the desired line.

    In this particular example, select the edge as shown below:

  7. Click OK.

    The Line Analysis Connection.1 connection appears in the specification tree under the Analysis Connection Manager.1 set.
