Apply a gravity load to a generative model
Learn how to apply a self-weight load to the generative model.
To turn on the gravity load
In the browser, click
next to a Load Case, and then click next to Loads to expand the loads in the load case.Select the Gravity option.
The Gravity load is checked in the browser.
To turn off the gravity load
In the browser, click
next to a Load Case, and then click next to Loads to expand the loads in the load case.Deselect the Gravity option.
The Gravity load is strikethrough in the browser.
To edit the gravity load
To modify the magnitude or direction of gravity:
In the browser, click
next to a Load Case, and then click next to Loads to expand the loads in the load case.Mouse over the Gravity node, and then click
.The Edit Gravity dialog opens.
Choose one of the following options for defining the gravity direction:
Normal. The gravity direction depends on what type of Reference entity you select, as follows:Face. The gravity direction is normal to the selected face.
Edge. The gravity direction is the average of the normal vectors of the faces on either side of the selected edge.
Vertex. The gravity direction is the average of the normal vectors of all faces that meet at the selected vertex.
Note: In all three cases, the vector points towards the solid body. Click Flip Direction
to reverse the vector (pointing it away from the solid body).
Angles. Specify a relative X Angle, Y Angle, and Z Angle to orient the gravity direction. If you want to align the gravity direction to a reference entity, select the entity, and then modify the angle from that reference entity.
Vectors. Specify the components of gravitational acceleration in the Fx, Fy, and Fz input fields. Be sure to include a minus sign if you want gravity to act in the negative X, Y, or Z direction.
Specify the magnitude of gravitational acceleration.
(Optional) Click Change Units
to choose alternative units for specifying the gravitational acceleration.Click OK.
