timestep too small, help!

[ICANSEEYOU7687]

I am trying to design a simple bubba oscillator, and I am getting a timestep to small.  I have tried a couple of the solutions found here

and

But it did not help or work at all and I am getting pretty frustrated.  Hopefully someone here can help me...

Here is my file, I am trying to get a transient analysis from 0.002 to 0.005 seconds, and I have tried timesteps from 1 second through 1e-7, and even when I changed my range to about 10 seconds, and told it to step by 1 second intervals, it still said my timestep was too small.  Pretty annoying...

Any help would be greatly appreciated!

Hi,

The op-amp model seems to be giving the simulator a hard time. The LF347N component also has the Texas Instruments/LT347_2 model that you can use (under Model manufacturer/ID. section of the Select a component dialog). Replace your component and select this model.

That seems to work as the simulation completes and the circuit oscillates.

Thanks,
