The
Remote Loads/Mass PropertyManager
allows you to apply remote loads, remote masses, and remote displacements for
static, nonlinear static, and topology studies.
For frequency,
linear dynamics, buckling, and nonlinear dynamic studies see topic Remote
Loads/Mass PropertyManager (for frequency, linear dynamics, buckling, and
nonlinear dynamics studies).
You cannot apply a
remote load or remote mass in a linear dynamic response spectrum
study.
To access the Remote Loads/Mass PropertyManager, do one of these:
- In the Simulation study tree, right-click the External Loads folder and select Remote Load/Mass.
- Click .
- Click Remote Load/Mass
(Apply Loads toolbar).
Selection

|
|
 |
Faces, Edges, or
Vertices |
- If you select a Rigid connection
type, you can select faces, edges, or vertices to apply
remote loads, remote masses, or remote translations and
rotations.
- If you select a Distributed
connection type, you can only select faces
.

Reference Coordinate System
Defines the coordinate system used for interpreting the location and
directions of the remote features.
Global |
The global coordinate system is
used by default. The global coordinate system is based on the Front
plane with its origin at the Origin of the part or assembly.
|
User
defined |
Click Select a Coordinate System
, then select a
coordinate system from the FeatureManager tree flyout. The global
coordinate system (Front plane) is used by default if no coordinate
system is selected. This system is used in interpreting the location
and directions of the remote feature. |
Location
Defines the coordinates of the reference node location.
 |
Units
|
Defines the units for the remote
node coordinates |

|
X-Location
|
X-coordinate of the point of
application of the remote load, mass, or translation with reference
to the selected coordinate system (or the global coordinate system).
|

|
Y-Location
|
Y-coordinate of the point of
application of the remote load, mass, or translation with reference
to the selected coordinate system (or the global coordinate system).
|

|
Z-Location
|
Z-coordinate of the point of
application of the remote load, mass, or translation with reference
to the selected coordinate system (or the global coordinate system).
|
Translational Components
Defines the remote forces and remote translations.
 |
Units |
Defines the units for the remote
loads and remote translations. |

|
X-direction |
Defines the value of a remote
force or remote translation in the X-direction. |

|
Y-direction |
Defines the value of a remote
force or remote translation in the Y-direction. |

|
Z-direction |
Defines the value of a remote
force or remote translation in the Z-direction. |
Rotational Components
Defines the remote moments and remote rotations.
 |
Units |
Defines the units for the remote
moments and remote rotations. |

|
X-direction |
Defines the value of a remote
moment or remote rotation in the X-direction. |

|
Y-direction |
Defines the value of a remote
moment or remote rotation in the Y-direction. |

|
Z-direction |
Defines the value of a remote
moment or remote rotation in the Z-direction. |
Connection Type
Distributed coupling
constrains the motion of the coupling nodes to the translation and rotation of the
reference node where the remote feature is applied.
The distributed
coupling constraint is enforced in an average sense in a way that enables control of
the transmission of remote loads and displacements through weight factors at the
coupling nodes. Distributed coupling allows the coupling nodes of the selected
geometry to move relative to each other.
Distributed |
For cases of more than a few
coupling nodes, the distribution of remote forces/moments and mass
is not determined by equilibrium alone, and distributing weight
factors scale the distribution.
Weighting Factor: Default
(constant)
|
Uniform weight distribution. All weight
factors wi are equal to 1.
|
Linear
|
Weight factors decrease linearly with
distance from the reference node.

|
Quadratic
|
Weight factors decrease with distance
from the reference node following a quadratic polynomial
formulation.

|
Cubic
|
Weight factors decrease with distance
from the reference node following a cubic polynomial
formulation.
 wi is the weight
factor at coupling node i, ri is the coupling
node radial distance from the reference node, and
r0 is the distance to the furthest
coupling node.
|
|
Rigid |
The coupling nodes do not move
relative to each other. Rigid bars connect the reference point to
the coupling nodes, and high stresses can develop as a result. The
faces where remote loads or displacements are applied behave like
rigid bodies. |
Mass
Defines the components of the remote mass.
 |
Units
|
Defines the units of the remote
mass components. |

|
Remote Mass
|
Defines the remote mass value.
|

|
Moment of inertia
|
Defines the mass moment of
inertia with respect to axis X. |

|
Moment of inertia
|
Defines the mass moment of
inertia with respect to axis Y. |

|
Moment of inertia
|
Defines the mass moment of
inertia with respect to axis Z. |

|
Moment of inertia
|
Defines the product of inertia
with respect to axes X and Y. |

|
Moment of inertia
|
Defines the product of inertia
with respect to axes Y and Z. |

|
Moment of inertia
|
Defines the product of inertia
with respect to axes X and Z. |
The mass moments of inertia are calculated with respect to a
coordinate system that is centered at the CG, and has X-Y-Z axes parallel to the
X-Y-Z axes of the global, or user-defined coordinate system.
Variation with Time
For nonlinear studies, you can define time-dependent remote loads.
Mass properties remain constant during the simulation.
Variation with Frequency
For harmonic and random vibration studies, you can define frequency-dependent
remote loads. Mass properties remain constant during the simulation.
