[Help] About the simulation of Wien-bridge OSC.

The Wien-bridge OSC is as below.

R=1K Ohms, C=1uF, so f=1/(2*pi*R*C)=159Hz. And the BW of the operational amplifier is 9KHz. Theoretically, the OSC outputs a sine wave.

However, the OSC keeps a common voltage, which is another steady state.

Is there something wrong with my simulation setup? Can you help me, please? Thanks a lot.

Thank you so much, Mr. Beckett.
I set the initial voltage of a cap to be non-zero with a DC supply. The OSC oscillated.
I shall try to use your method, Mr. Beckett.
Thank you.
