Thanks for your reply. 

May I ask is there a rule of thumb for setting the time step in modeling? For example, in a CFD world, there is Courant Number to follow?

Also, I am not sure if it is still the time step problem which led to some negative temperature in the first couple dozen steps.

Thank you.
