Hello guys , i'm trying to calculate , with flow simulation , a force generated by the rotation of my propeller . I don't know why but when i try to show the flow trajectories , those trajectories seems to be good , but i can't obtain any force or any difference of presure/velocity. If someone could help me to fix this , that would be very kind.
Some screenshots of my flowsimulation parameters :
(All those screenshots will be in french , sorry about that)

It's kind of hard to tell without having your project available. Could you upload it to the forum?
If not, try generating a couple of cut plots through the midplane of the propellor. Do one for pressure and one for velocity (including 2D vectors) and maybe we can find out the problem. Make sure to turn off "use CAD geometry" and "interpolate".
