Hello Community,
I'm currently working on a backward facing step and have some troubles in understanding how I get information about the reattachment point.
I read some theory:
I have to find the sheer wall stress at the point where it changes from a negative to a positive value. The problem is that I don't know which data I need to use and read. Do I need to use the data from the last iteration time step to which the solution converged? And is there anything else which I need to post process?

Thanks for your help!
