I am trying to simulate a litle propeler rotation in air: I wan to get the Fy force :
The results are OK with my experiment at slow angular frequency but when w>3000 rad/s there are some errors (see below).
I have a warning saying that "there is a lot of supersonics cells... Try to use manual criterium" .... Is that the problem ?
Can you help me to avoid this problem please ? (perhaps by adding some initials conditions ??)
I have add a criterium (F <0.1N) but simulation is very long... and still do not converge to my experiment value...
Thanks you very much for you help.
