Set linear global loads in the Simulation workspace

Global loads are applied to all parts or bodies in the study. Only one global load can be applied per study.

These instructions assume you are setting up one of the following studies:

structural buckling icon Structural bucklling

static stress icon Static stress

nonlinear static stress icon Nonlinear static stress

modal frequencies icon Modal frequencies

shape optimization icon Shape optimization

  1. In the Simulation workspace, Setup tab, select Loads > Linear Global Load linear global load icon.

  2. In the Linear Global Loads dialog, choose one of the following two Direction Type options:

    • 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 entity.

      The local coordinate system orientation depends on the type of entity selected, 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.

    • 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. Optionally, click override units icon Override Units to choose alternative units for defining the linear global acceleration. Then, choose the desired units from the drop-down list.

  4. Specify the Magnitude of the linear acceleration or the X, Y, and Z acceleration components, depending on your selection in step 2.

  5. Click OK to apply the load and close the dialog.
