How to define yplus by oneself!
I want to use a damping function-fmu in my udf, and the expression of fmu contains yplus. As you know, we can only get the wall yplus in fluent, so i plan to write a udf to define the yplus by myself，which changes with the distance from the wall.
Anybody have done this work or similar to it,please tell me how to write? Which macro could i use? Are there some udf examples relate to it? Thanks very much!!
Any help would be much appreciated. Micheal.
