Create and accelerations by applying a load, representing accelerations, to nodes or
sets.
Configuration 9 - Acceleration loads allow for an
acceleration (length/time2) to be defined on the model.
Accelerations are displayed as a vector with the
letter A at the tail end in the modeling window.
Note: In the Radioss, Abaqus, and LS-DYNA profiles,
load entities are created immediately upon entering the tool. Use the Entity Editor to modify any properties. In all other solver
profiles, load entities aren't created until you make your selections then click
Create.
From the Analyze ribbon, click the Accelerations
tool.
Figure 1.
Note: In the OptiStruct,
Nastran, and Abaqus profiles, first click the Body
Forces tool then select Accelerations
from the secondary ribbon.
Select the keyword to create from the Load Type menu.
The available types depend on the current solver interface.
If necessary, choose the entities to which the acceleration will be
applied.
Define the acceleration's direction relative to a local coordinate system or
the default global system.
Specify the magnitude and direction of the acceleration.
Constant Components
Specify the direction and magnitude of the load by entering the X,
Y, and Z values of the components.
Constant Vector
Specify the magnitude, then use the plane and vector tool to specify
the vector along which the load should act.
Curve Components
Specify the X, Y, and Z components to define the direction and
magnitude, for example, (2,2,2) will be twice the magnitude of
(1,1,1). Next, select an existing curve. Last, specify a factor for
the curve’s xscale to use the same curve for many different cases,
but vary the scale of its intensity or time to match the needs of
your current load.
Curve Vector
When working with loads that are time dependent, use this method to
first specify a magnitude (yscale) for the curve. Next, select an
existing curve, then use the plane and vector tool to specify a
direction, if necessary. Last, specify a factor for the curve's
xscale to use the same curve for many different cases, but vary the
scale of its intensity or time to match the needs of your current
moment.
