Ellipsoids Panel

Location: Analysis page > Safety module

Ellipsoids can be created at finite element nodes or geometric points. When an ellipsoid is created, it is placed in the current multibody collector specified in the Model Browser. If a current multibody collector has not been specified, a collector is created automatically.

Create Subpanel

Option	Action
base name	Specify a name for the ellipsoids (max length of 160 characters).
coordinates /entities	Select a method of determining the ellipsoid center.
center x /y /z	Specify the X, Y, and Z coordinates of the desired center of the ellipsoid. Note: Only available when coordinates is selected.
nodes /points selector	Appears when entities is selected. Note: Only available when entities is selected.
multibody	Associate the ellipsoid with an existing multibody.
radius definition	by value Specify the length of the ellipsoid's A, B, and C axis respectively. by vector Specify the length of the A, B, and C axis as the distance between the ellipsoid's centroid to the selected axis nodes. The by vector radius definition option also specifies the orientation of the ellipsoid by using the A node to define the A axis and the B node to define the A-B plane.
A =	Specify the axis length.
B =	Specify the axis length.
C =	Specify the axis length.
N =	Define the shape factor of an ellipsoid. This is the "order" of the ellipsoid; higher numbers make the ellipsoid more rectangular. Typical values range from 2 to 10, because above a certain number the differences become very slight.
color	Select a color for the ellipsoid.
orientation	body system Align the axis of the ellipsoid along its collector's local coordinate system. If a current multibody collector is not specified in the Model Browser, both the created ellipsoids and auto-created collector are aligned with the global coordinate system. create system Define the ellipsoid coordinate axis. The functionality is the same as the local coordinate system creation in the Systems panel. system Define a local coordinate system. When the ellipsoid is created, the selected system will be copied to the ellipsoid's centroid.
create: ellipsoide	Create an ellipsoid.
create: cylinder	Create a simple cylinder.

Update Subpanel

Option	Action
ellipsoids selector	Choose the ellipsoids that you want to update.
radius definition	by value Specify the length of the ellipsoid's A, B, and C axis respectively.
A =	Specify the axis length.
B =	Specify the axis length.
C =	Specify the axis length.
N =	Define the shape factor of an ellipsoid. This is the "order" of the ellipsoid; higher numbers make the ellipsoid more rectangular. Typical values range from 2 to 10, because above a certain number the differences become very slight.
color	Select a color for the ellipsoid.
orientation	body system Align the axis of the ellipsoid along its collector's local coordinate system. If a current multibody collector is not specified in the Model Browser, both the created ellipsoids and auto-created collector are aligned with the global coordinate system.
create: ellipsoide	Create an ellipsoid.
create: cylinder	Create a simple cylinder.

Command Buttons

Button	Action
create	Create the ellipsoid/cylinder.
reject	Revert the last changes.
update	Update the ellipsoid with the recent changes.
review	To review an ellipsoid's current settings without changing them, select the ellipsoid and then click review.
return	Exit the panel.
