Capacitor doesn't work with op-amp #18

The simulator does not work with a simple integrator circuit. An integrator contains 1 capacitor, 1 op-amp and 1 resistor. The error message says there is an unknown error in the circuit.

The simulator can normally support 1 capacitor/inductor/diode. I don't see why this circuit breaks it.

There is an op-amp in there so that might be the problem. When replacing the capacitor with an inductor or a diode, the transient analysis works. Only the capacitor seems to break the simulator in this case.

The transient analysis works out the effective thevenin equivalent R and C. in this case that does not exist - you can't do transient analysis on this circuit. there should be a more informative error message.
