Point Load (on Axis)
A Point Load (on Axis) node can be added to points located at R = 0 in axially symmetric models. This is the only true point load an axisymmetric model, since loads applied at points having nonzero radial coordinates actually represent a ring load. You can add a ring load using a Ring Load node.
Force
Enter values or expressions for the Force Fz in the axial direction.
•
The Load list normally only contains User defined. When combining with another physics interface that can provide this type of load, it is also possible to choose a predefined load from this list.
•
You can add the Phase subnode to specify the phase of this load in a frequency domain analysis.
•
You can specify this load to be a Harmonic Perturbation in a frequency domain analysis.
•
You can assign this load to a load group. See Load Cases in the Structural Mechanics Modeling chapter.
