Output of Inverting opamp with single supply
Vout is not the output of your opamp. If you would add another tag and check the actual output of the opamp you will see it is always set on 0V because you have an inverting configuration without a negative rail so you force the opamp towards the ground voltage which is 0V.

So, the output of the opamp can be looked at like 0V, the same as if the diode's anode would be connected to ground. The input of the opamp has almost no current flowing in so it is almost an open circuit. The diode is also reversed biased so can be looked like open circuit. Finally, you get a voltage source with two resistors is series and you are checking the voltage on the farther away one, this will be the same voltage as the voltage source because all the voltage falls on these two resistors.
