Why are the du/dy values so low?
i am using ANSYS CFX 12. I am running a simulation of an empty computational domain. i used a log law profile to input the velocity at my inlet. When i checked the du/dy in CFX POST, i get values that are very small near the wall. This shouldnt be the case. du/dy should be large near the wall. Instead of getting values like 2000 plus, i get values near the range of 50 to 60. What is wrong? Can somebody help? my simulation is for a smooth wall.
