Hi All,

I am trying to analyse the width of the wake behind a circular cylinder and to do so I am looking at plotting the location of the separation point for different reynold's numbers. I am trying to use an expression in CFD post to return the coordinates of a point on the cylinder wall where the wall shear stress is zero but I dont seem to be able to do it, can anyone offer me any advice how to do this?

Thanks

Rob
