I want to calculate the fRe for water in a triangular duct with FLUENT,but i have a problem, Please help: I can use from formula((( f=tw/0.5ROU.U^2 ))) but for calculating the tw[wall shear stress] I use a point on the body of triangular and using from the below steps in Fluent: Report Surface integrals Report type: Vertex average field variable: wall fluxes surfaces: point 1 (for example) and the result give me an answer that will be differ from point 2 or point 3 or any other point, please let me know how I can get a report from average of tw in the duct??
