• Proceed similarly as above to set properties for the outflow BC
Name: outflow
Type : Outflow
General p r o p e r t i e s :
− Outflow Type : Pressure
− Outflow Data Source : From Boundary Conditions
− Outflow Pressure : 0
Backflow p r o p e r t i e s :
− Backflow Volume Fraction of Phase 1: 0.0
− Backflow Volume Fraction of Phase 2: 1.0
− Backflow t o t a l temperature : 0.0

Name: symmetry
Type : Symmetry

Assigning Boundary Conditions:

• Select Y Min in the drop-down list at the top of the BCs tab

• Highlight YMin 0 in the surface tree by clicking it

• Check Wall1 in the list of boundary conditions at the bottom of the page

• Click

Once the the assignment is done, the surface Y min 0 will be highlighted in the graphical window
on the right.

• Proceed similarly to assign the remaining surfaces to their respective boundary conditions.
The assignments of the remaining boundary conditions can be found below.
Boundary : X Min
XMin 0: symmetry

Boundary : X Max
XMax 0: symmetry

Boundary : Y Max
YMax 0: outflow

Boundary : Z Min
ZMin 0: symmetry

Boundary : Z Max
ZMax 0: symmetry
