Dear Ulf,
Thanks for your immediate answer.
I used
stream Tracer to produce streamlines from my files. Am I right?
I haven't think to this ratio (temperature/Peclet number of the system) yet, I should calculate it to see how big is the fluctuation. Good advice!

Dear George,
Thanks for your answer and the movies. Unfortunately, although I tried a lot I could see only the first movie. In my try for the last 3# ones, It said that
it is currently unavailable! Is there any other link for these? I really like to watch them.
As you mention, Maybe everything drowns in fluctuations. I should check for the magnitude of fluctuations.
