Does NI Multisim simulates op-amp input and output noise?
10uV/rt(Hz) is a really noisy op-amp. Most/average ones are about 50nV/rt(Hz).

If you are unsure then look for noise on your transient analysis screen - I'm presuming (not having used Multisim) that you can adjust the transient analysis screen so that the Y axis is just a few micro-volts top to bottom?

Another way around this is to approximately calculate what the noise amplitude might be at the inputs and add a voltage source that generates noise or even a sinewave. For instance if you have 100kHz bandwidth and the op-amp noise is 10nV/rt(Hz) then the equivalent input RMS noise voltage will be 3.16 uV. If you multiplied this by 6.6 you get a decent representation of p-p noise. Next, set your added voltage source to be this amplitude.
