    Anyone know what's causing the problem?

    I'm attempting to run an AC Sweep on the circuit below.

    Keeps coming up with a simulation error and not even an option to add a trace is showing. Any tips?

    Chucky, it seems that C27, C28 and C29 are paralleled by a short circuit.

    Thanks for the response, how would I fix it?

    t was an error that occured during the drawing and placing the part.
    Thus, simply remove the C and the wire and place C again.

    Delete the short circuits (the lines going through those caps).

    Done both and the error's still occuring, might it be the result of some extra nodes? The new circuit is here:

    Exactly what is the error message?
    I don't know how fussy Pspice is over drafting, but are the left end of R39 and pin 4 of U19a both properly connected?
    Is R32 really 13u ?

    Your circuit has too many opamp (64 nodes). You need full version not a demo.

    Replace all real opamp models by the ideal simple model called OPAMP.
    Note that this model does NOT need separate supply rails. Instead, you can EDIT (double-click the symbol) the power suppplies, which from the beginning are +-12 Volts.
