-
From the Loads section
of the action bar, click Force
.
- Optional:
Enter a descriptive
Name.
-
Select the geometry supports in the model.
A force can be applied to one or more points or faces. If you
select a model face, the force is distributed evenly across the surface.
You can also select a coupling connection, rigid
body, or rigid surface; the force is applied to the reference point for the
feature.
-
Enter the magnitude component for each direction of the local feature triad
(Force X, Force Y, and
Force Z).
For a cylindrical local axis system, the X-, Y- and Z-components are the R-,
-, and Z-coordinates, respectively.
-
Select an axis system and an axis.
Option | Description |
---|
Global
|
Aligns the local feature triad with the global coordinate
system. |
Local |
Aligns the local feature triad with a selected axis system in the
model. If you select this axis system, you must also specify whether the
axis system is Cartesian or
Cylindrical. |
Specify |
Allows you to orient the local feature triad directly. Right-click
the feature triad glyph on the model to orient the local feature
triad. |
Implicit
|
Aligns the axis system to the transformed axis system applied on the
support. |
-
Optional: Enter a Scale factor.
A scale factor is a multiplier used to scale the magnitude values.
-
Optional: Specify an
Amplitude and
Phase angle.
The amplitude curve defines the magnitude of the feature during the step. The phase
angle for the amplitude curve determines the real (in-phase) and imaginary
(out-of-phase) parts of the magnitude. A phase angle of 0º indicates a value
with no imaginary component. Note:
Phase angles are available only for a
harmonic response simulation step.
-
For random vibration steps, specify the PSD (power
spectral density profile) that describes the frequency profile of the real and
imaginary components of the force loads.
The Correlation field indicates the number of
other force loads that share the same PSD profile.

OK.
