I've been toying around with the coalCloud class, and had a questions about the constant rate devolatilization model. If I set the rate constant to something large (say on the order of 1/dt), it appears from the code (the calculate function in ConstantRateDevolatilisation.C), it seems that the entire mass of the parcel should be transferred to the carrier phase.

I've run some tests and there ARE volatile species transferred into the carrier phase, but the amount is far less than it should be. The summary for the spray cloud says that the right amount has been transferred to the carrier phase, but the total introduced is nowhere near what it should be. Are there any additional assumptions made in this model that I should be aware of?
