hiii..
i'm doin an A.C. electromagnet non-linear analysis on ansys. for loading the electromagnet i've coupled an independent voltage source with a 3-D circuit coupled stranded coil. but the solution is givin an error like this..

" The value of EMF at node 4337 is 1.65084963E+28. It is greater than
the current limit of 1.E+25. This generally indicates rigid body
motion as a result of an unconstrained model. Verify that your model
is properly constrained."

node 4337 is located in the solid coil where i've given the load.

so i wanna know what could be the mistake in my model. please help.
