This data setup allow the user to handle the boundary conditions applied to the velocity components on walls. Walls are identified according to the orientation of their normal vector from the adjacent fluid-cell. They are named as :
A data set can be attributed to the walls of several solid bodies. Some examples are given here .

Find here how to construct the wall boundary conditions and some examples.
For a sake of clarity, the data are defined for the the “WEST” wall and for the I-velocity component only. The user can easily define the boundary conditions related to the other walls and other velocity components by substituting the relevant character strings in the name of variables.
