[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.

Whilst it is lovely to see a picture of your circuit, I assume there was a reason you shared it rather than just wanting everyone to admire your handiwork?
