– Inflow Velocity components: u: 0.1 v: 0.0 w: 0.0

• Click to save the settings and close the window

• Proceed similarly as above to create the following boundary conditions.
Name: outflow1
Type : Outflow
Properties :
− Outflow Type : Pressure
− Outflow Data Source : From Boundary Conditions
− Outflow Pressure : 0

Name: wall1
Type : Wall ( use default values )

Assigning Boundary Conditions:

• Select boundary XMin in the drop-down list at the top of the BCs tab

• Highlight XMIN 0 in the surface tree by a simple click

• Check inflow1 in the list of boundary conditions

• Click

After completion of the assignment, the XMin 0 surface will be highlighted in both the the surface
tree and the graphical viewer with the corresponding color in the boundary condition table (see
the column to the right of the Type column).

• Proceed similarly as above to assign the remaining surfaces to their respective boundary
conditions.
Boundary : XMin
XMIN 1 ( Step face ) : wall1
Boundary : XMax
XMax 0: outflow1
Boundary : YMin
YMIN 0: wall1
YMIN 1: wall1

Boundary : YMax
YMAX 0: wall1
