A Simile model instance must be reset before it is first run, whenever the parameters are changed, and in order to run it again with new values for random constants.
1  reset.model(instance.handle, depth, integration.method, starting.time)

instance.handle 
The handle returned by create.model(), identifying an executable model instance. 
depth 
Simile does a sort of 'lazy execution', with values being left untouched if they do not need to be recalculated for a given type of reset. This argument tells it what to reset, with each action including those that follow it:

integration.method 
One of "Euler" or "RungeKutta", the latter being 4thorder. Default is "Euler". 
starting.time 
Value for model time after resetting. Used for indexing time series, time plots etc in the model. Default is 0. 
None
