Set a linear global load in the Generative Design workspace

To define the linear global load, you need to select geometric objects on the preserve geometry. You can apply one load per study.

  1. On the Define tab, click Design Conditions > Linear Global Load linear global load icon.

    The Linear Global Load dialog opens.

  2. Choose one of the following Direction Type options:

    a. angle load direction icon Angle (delta): Choose a Reference flat face, cylindrical face, or straight edge on which to base a local coordinate system. A vector arrow and arcs with manipulators appear on the screen. Optionally, use the manipulators to drag the vector angularly relative to the original direction. You can also specify a rotation angle numerically in the X Angle, Y Angle, and Z Angle input fields.

    Note: The X, Y, and Z angles do NOT correspond to the global axes. They are based on the local coordinate system of the selected reference geometry.

    The local coordinate system orientation depends on the selected geometry type, as follows. In all cases, the acceleration vector points in the Z direction of the local coordinate system:

    • Flat Face: The acceleration vector is normal to the selected face and points toward the solid body.
    • Cylindrical Face: The acceleration vector is parallel to the axis of the cylindrical face. The selection can be a full (360°) or partial (<360°) cylindrical face.
    • Straight Edge: The acceleration vector is the average of the normal directions of the two flat faces that are adjacent to the selected straight edge. When an edge is the intersection of a flat face and a tangent cylindrical face, the vector direction is 45° relative to the flat face's normal direction.
    Note: (Optional) Click Flip Direction load direction flip icon to reverse the load direction.

    b. load direction - vectors and components icon Vectors (x, y, z): Specify the X, Y, and Z components of acceleration based on the global coordinate system.

  3. In the Acceleration Components section:

    a. Specify either of the following parameters, depending on your selection in step 2:

    • The Magnitude of the linear acceleration, or
    • The components of linear acceleration about the X, Y, and Z global axes.

    b. (Optional) Click override units icon Change Units to choose alternative units for defining the linear global acceleration. Then, choose the desired units from the drop-down list.

  4. Click OK.
