A very convenient way to “simulate” a potentiometer in the simulator is to use the “tune” function in the top menu at the mouse cursor.
If you click it, then you can click any resistor or capacitor in the schematic and it will be added to the “Tune” area. There you can enter maximum and minimum limits and then use the slider to adjust, or directly type a value in the middle box.
In your particular case, just replace the potentiometer with a normal resistor in the schematic, and connect the non-inverting pin to the net between the resistors and use the tune function to “tune” the lower resistor.
This way you have live update of your simulation results when you’re sliding the slider.
