Thanks, Brent. Good call.
I hope that down the line the seed can be based on computer time and not simulation time because stochastic modelling is going to require grater random number generator capabilities.
Cheers,
Liam

This doesn't suit my application very well because I specifically want a probability distribution on the annual energy use. Does anyone know of how to get more randomness (even if it's faking it somehow)?
