3D UDF parabolic velocity profil
 
Hello
I have worked out with 2d udf for parabolic velocity inlet.
Please help me how this code will change with 3d (Inlet in a circular face). I want to know how will be the equation considering 3rd dimmension.
as in 2d we have V(x)=Vmax- y^2/(disatnce from centre in y direction )^2 * Vmax.
