Linearly Accelerated Frame
When you add a Linearly Accelerated Frame node, inertial forces are applied to all selected features in the physics interface with a density, mass, or mass distribution. You select boundaries, and all edges and points which belong to the selection are automatically included.
Shell Properties
Select the layer or layers to which the frame acceleration force is to be applied.
Table 6-48: Layer Selections; linearly accelerated frame.
Selection
Use All Layers
Selection of Individual Layers
Boundary
Same as interface selection when the node is added.
When Use all layers is not selected.
Only a subset of the layers selected in the interface can be selected.
•
All other settings for the Linearly Accelerated Frame node are described in the documentation for Linearly Accelerated Frame in the Solid Mechanics interface.
•
For a general description of layer and interface selections, see The Shell Properties and Interface Selection Sections.
•
You can assign this load to a load group. See Load Cases in the Structural Mechanics Modeling chapter.
