Eigenfrequency of piezoelectric devices with an electrical circuit

Please login with a confirmed email address before reporting spam

Hello.

I am trying to see the effect of a load on the eigenfrequency of a piezoelectric device. (piezoelectric on silicon)

I have modeled the piezoelectric film (+the silicon wafer) and I have added a resistor using an electrical circuit on the piezoelectric film.

I do not find a way to solve the problem as i always get "Failed to evaluate variable Jacobian".

Moreover, this model worked very well on 3.5a using the spice editor.

I attach the model.

Any idea to solve this problem on 4.2 ?

With many thanks,
SB
