Rotating Frame
Centrifugal, Coriolis, and Euler forces are “fictitious” volume forces that need to be introduced in a rotating frame of reference, since it is not an inertial system. Use a
Rotating Frame
node to add the effect of these forces. The forces are generated by all selected features in the physics interface having a density, mass, or mass distribution. You select boundaries, and all edges and points which belong to the selection are automatically included.
Shell Properties
As a frame rotation always acts on the entire structure, it is not possible to select individual layers. The selection in this section only acts as a filter for the boundary selection.

Rotating Frame
in the Solid Mechanics interface.
