Analysis Types
Velocity is available for the following analysis types:
Explicit Dynamics - For Explicit Dynamics analyses, the Y Component (that is, Θ direction) of a velocity constraint defined with a cylindrical coordinate system has units of angular velocity.
Dimensional Types
The supported dimensional types for the Velocity boundary condition include:
3D Simulation
2D Simulation
Geometry Types
The supported geometry types for the Velocity boundary condition include:
Solid
Surface/Shell
Wire Body/Line Body/Beam
Topology Selection Options
The supported topology selection options for Velocity include:
Body
Face
Edge
Vertex
Avoid using multiple velocities on the same vertex.
This boundary condition cannot be applied to a vertex scoped to an end release.
Define By Options
The supported Define By options for the Velocity boundary condition include:
: Supported for 3D Faces only.
Entering a zero for a component sets the Velocity to zero.
Entering a blank for a component allows free velocity in that direction.
Magnitude Options
The supported Magnitude options for Velocity include the following:
(Time Varying)
(Time Varying)
Applying a Velocity Boundary Condition
To apply a Velocity:
On the Environment Context tab, click Supports>Velocity. Alternatively, right-click the Environment tree object or in the Geometry window and select Insert>Velocity.
Define the Scoping Method.
Select the method used to define the Velocity: Components (default) or Normal To.
Define the loading data based on the above selections.
