Is the ground_reference parameter refers roughness length of the ground? How to input roughness length value for log law?

Hi I'm planning to study the variation of ground roughness length on wake recovery. Can I know how to vary the ground roughness length?
Also what is the difference between log and turbsim?

[drijazfazil]

Also Can you guide me how to run this file / call this api, to generate tubsim boundary condition?

Hey,

Go ahead and email me. We can set up a meeting to chat since it will be easier to discuss this face to face.

Best,
Jeff
