You can create a rotational body force load to define
loads resulting from rotation of the model. You can specify either angular
velocity or rotary acceleration. Abaqus defines the load by using the square of
the angular velocity or by using the acceleration directly. In either case, the
load definition must include an axis of rotation, which is defined as follows:
- If you are working in three-dimensional space, you define the
location and direction of the axis by entering the global coordinates of two
points.
- If you are working in two-dimensional space, you specify the location
of the axis by entering the coordinates of a point in the plane. The direction
of the axis is always out of the plane.
- If you are working in axisymmetric space, the axis is always in the
location and direction of the positive global Z-axis.
You can define a rotary acceleration force only in two- or
three-dimensional space.
