Hello all,


I am simulating the turbulent flow over a circular cylinder of uniform cross section. Because I intend to compute the flow with the approximation of an infinitely-long cylinder (i.e., without end effects), I am using the cyclic boundary condition for the sides of the cylinder. I was wondering if when using surfaceFieldValue or PatchIntegrate to integrate the wall shear stress over the body gives a result in units of length or if OpenFOAM actually considers the length of the cylinder in my grid geometry. Can anyone help? I have not been able to find anything specific on this, and I am not proficient in reading OpenFOAM's code.


Thanks
