Hi all,
I am simulating channel flows using openfoam, I can show wall shear velocity U_tau when the calculation is done. But now I want to monitor U_tau during simulation, how can I do this? Thanks guys. |

Suppose that you are using channelFoam, than the pressure gradient (which is printed out during the run as an info) is equal to the wall shear stress (if your channel height is 2m) which is, at the end, square of the u_tau (of course if the rho=1).
