If I have, say, a 1/4 symmetry model of a straight cylindrical pipe (with two symmetry boundary conditions) do I input 0.5*diameter in the turbulence specifications as the hydraulic diameter? Or is the correct hydraulic diameter the actual diameter of the full model?February 18, 2022 at 7:16 amMurari IyengarAnsys EmployeeHi FluxLimited The hydraulic diameter value needs to be equal to the diameter of the full model. Although you are simulating 1/4 of the model using symmetry, the diameter does not change, thus the hydraulic diameter also remains the same.
