It is greater than<br /> the current limit of 1.E+25. This generally indicates rigid body<br /> motion as a result of an unconstrained model. Verify that your model<br /> is properly constrained."</p> <p>node 4337 is located in the solid coil where i've given the load.</p> <p>so i wanna know what could be the mistake in my model. please help. </p>
