Modelling 555 timer behaviour

I fairly new to Circuit Lab. I want to model the behaviour of a 555 timer based monostable circuit designed to switch on a relay for 15 seconds or so based on one pulse to the trigger. How do I model the momentary grounding of the trigger and then the circuit response over time? Any help would be much appreciated.
