BL separation rotating Tire
 

Dear All,

I'm doing a study on rotating wheels with a lattice boltzmann code. I'm running against an issue of recognizing where the boundary layer is going to separate. I got all the post-processing results and both pressure and velocity graphs. However the flow is so transient that it's quite hard to see the exact separation point.

Is there anyone who ran against such an issue, or got some tips or solutions in how to see the separation point easily.

Thanks,

Yuriy
