Faulty LM358 SPICE model

I'm trying to find a working spice model for the ST LM358. The one on the site gives an output of -12KV for a small sine wave when powered from ± 12V

And the "contact us" email doesn't work.

So first try your circuit with a basic opamp model, first order compensation, as the lm358 is almost exactly like that.

And then compare the output....and correct your circuit. :) 

Because a simulation doesn't care about 10kV at 10kA in your circuit - all just numbers, coming from the calculation of the network. So if you have any open output or something like this, the result of the simulation just shows unrealistic results, what indicates: some start parameters or circuit elements producing this. Almost every time a error in the circuit.
