HI,I have a circuit that generate a sine wave based on hartley oscillator but i added an OP_AMP ic to circuit screen board in proteus that is not connected to any thing but when exists in board outpu of oscilloscope is nothing but when i delete OP_AMP from screen everything works good and oscilloscope shows generated sine wave ehat is problem?why this occur?is this a proteus problem or i can handle this problem?
it gives this error : [SPICE]Gmin step[110 of 120] failed:GMIN =5.62341e-012
what this error means?
here is my circut:
