Thank you! I just returned to work yesterday from a vacation. I will try to do it like that and tell you the results.
I try to use the boundary layer mesh. The appropriate velocity field could be obtained, but the concentration field was not right (some of the values much exceeded the expectable largest value, and some were much negative). Now my computer memory is enough. However, I do not get the proper results so far.........
