Hello everybody,
I have a question regarding the timestep in a transinet simulation. I am simulating combustion and in same points the tempertures seems to jump very easy from one small value to a big one and after that jumped back, which is not the case in reality. The convergence in satisfactory < 1e-4 owith each timestep. My question is if the large variations of temperature (this doesnt appear at the start of the simulation) are due to the size of timestep, too big maybe?? How can i know which is the most appropriate timestep??? caty |
