AC voltage source in frequency linear perturbation

Please login with a confirmed email address before reporting spam

Hi,

In the loudspeaker model, there are three physical fields:solid,magnetic and acousitic and two study steps:stationary and frequency domain-linear perturbation. i add a short-circiut ring in the model and want to simulate it as a transformer,so i add the electrical field, but the type of voltage source:AC-source seems to be active only in Frequency Domain studies and cannot be used in frequency domain-linear perturbation study.i tried to set Vsrc as 4[V] or linper(4)[V],the results are eigher 0 or very small,can someone tell me how to set these study steps and parameters to make it correct? thank you
