configurations using Adams/View, first create a marker whose position is coincident with its attachment
point and then modify it.
• Configuration 1: Position and Attachment Node are Coincident
• Configuration 2: Position and Attachment Node are not Coincident
• Configuration 3: Attached to Multiple Nodes
Configuration 1: Position and Attachment Node are Coincident
This is the default marker configuration that Adams/View creates and the only one that Adams/Solver
(FORTRAN) supports. This configuration is suitable for creating measures and applying concentrated
point loads at the attachment node.
To create a marker whose position and attachment node are coincident:
1. From the Geometric Modeling tool stack of the Main toolbox, select the Marker tool .
2. In the marker construction container, select Add to Part.
3. Following the instructions in the status bar, select the flexible body to which the marker will be
attached. Then, click the node closest to the position you want to place node.
Adams/View positions the marker at the closest node and attaches the marker to the same node.
Configuration 2: Position and Attachment Node are not Coincident
It is often necessary to add a marker to a flexible body where there is no node. For example, you may
need to connect two flexible bodies whose nodes are not coincident or apply a force at a location offset
from a node.
A similar marker configuration which is compatible with the Adams/Solver (FORTRAN) can be
obtained using massless links. The massless link is attached to the flexible body at the desired attachment
node using a fix joint. Subsequently, a marker is attached to the massless link at the desired position. For
more information about massless links, see Using Massless Links.
To create a marker whose position is offset from its attachment node:
1. First create a marker which is positioned at the node you wish to attach it to following the steps
in Configuration 1: Position and Attachment Node are Coincident.
Now modify the marker.
2. Right-click the marker you just created, and then select Modify.
The Marker Modify dialog box appears.
3. In the Location text box, enter the desired position of the marker. You can either type in the
coordinates directly; or right-click the Location text box, select Pick Location, and then click the
desired location with the mouse.
4. Select OK.
