wire : is a member cycle

[anas_saad]

hello, I am trying to create a model of a linear motor. I used the simulation subsystem but it appear an error message wire : is a member cycle. I tryed to use a feedback node (in the main vi). It executes but it shows a wrong response. Can you plsease help figure out what is the problem. Thank you.

PS: the are two attached images that shows the part that includes the problem in the main VI and the simulation subsystem.

That error is a fancy way of saying you hooked up the thing to itself.

Inserting a feedback node is probably the right thing to do. The wrong response you get might be cause by the value you use to initialize the feedback node.
