Hello,

I calculate the flow in arteries and I would like to show that for some time steps the wall shear stress has the opposite direction, for example in the curves, branches, etc. For the straight pipes it is easy but how to do it for the more complicated geometries? I need to find indicator that will tell me that the flow change diections (mostly next to the wall) then I can simple add a sign (-) to the shear stress/shear rates.
