Op-amp outputting very large voltage (bug?) SOLVED

I am having issues with a circuit. When I simulate it in the "Time domain" the op-amp seemingly puts out a great many kV. Is this a bug?

@Jodes,

No, it's not a bug.

Your CL circuit uses an opamp model which has no supply rail limits so it can generate an output that may be far higher, or lower, than a real opamp can achieve.

Since you are using the opamp open loop (in effect as a comparator) the output will swing to whatever CL allow their rail-less opamp model to swing up and down to.

You might be better using their 5 pin railed model which has outputs defined by the supply rails.
