I am getting the following error in my analysis
**ERROR** DEPENDENT NODE xx IS BEING DEFINED AS DEPENDENT TO CONTROL NODE yy WAS PREVIOUSLY A DEPENDENT TO A PRIOR CONTROL

Can you please let me know what is the problem ?

 

A Dependent node (formerly Slave Node) cannot have more than one Control Nodes (formerly Master Node). The error that you have encountered is typically generated when that happens.

For example let us say you have nodes 51 52 53 and 54 that are defined as dependent nodes to control node 100
DEPENDENT FX FZ CONTROL 100 JOINT 51 52 53 54

If the same set of nodes are defined as dependent to control node 200 also as shown next
DEPENDENT FX FZ CONTROL 200 JOINT 51 52 53 54
you would get the error that you are encountering with your model.

So the solution would be check for such duplicate control node assignments and take those out.
