Now I am reading your paper. That is "Sedimentation Scour Model" Gengsheng Wei, James Brethour, Markus Grünzner and Jeff Burnham.2014
and in Scour at cylindrical piers part like attached Figure. Please help me to explain about boundary condition such as: Xmin. Xmax, Ymin Ymax, Zmin, Zmax in FLow 3D Program
Thanks you so much
i am using Flow 3D program to simulate the scour around the cylindrical piers. I dont know about boundary condition such as: Xmin. Xmax, Ymin Ymax, Zmin, Zmax in FLow 3D Program.
Use this forum it may be helpful. Good luck.

In my recently project and order to apply the boundary conditions, the Symmetric boundary condition was applied to the top boundary, the Specified Velocity boundary condition was applied as flow input and the Outflow boundary condition was applied to the downstream boundary. The outflow B.C. is applied to prevent the effects of the outside conditions of the solution network. Also, the Wall boundary condition was defined for walls and channel bed which act as virtual frictionless walls.
