The next step is to associate each boundary surface with its corresponding boundary condition.

• For that, click the drop-down list above the surfaces tree and select .

• Next, select the Xmin 0 surface in the surface tree by simply clicking it and check the Wall
in the list of boundary conditions.

• To complete the assignment of the surface to the adequate boundary condition click .

• Proceed similarly to assign the remaining boundary surfaces to their coresponding boundary
conditions as described below
Boundary Xmin 0: Wall
Boundary Xmax 0: Wall
Boundary Ymin 0: Wall
Boundary Ymax 0: Wall
Boundary Zmin 0: Symmetry
Boundary Zmax 0: Symmetry

The window should look similar to Figure 4.8 after the assignment of all the boundary conditions.

4.2.5 Input Tab
The simulation parameters can be set up by clicking the Input at the top of the TransATUI. The
parameters of the simulation can then be defined by selecting and completing the fields of the
different tabs.

• Click Input at the top of the TransATUI

4.2.5.1 Physical Models Tab
• In the Basic Equations section of the Physical Models tab, check the following equations
that are to be solved for during the simulation (see Figure 4.9)
Basic Equations :
Pressure : ON
U v e l o c i t y : ON
V v e l o c i t y : ON

• Activate Gravity and click to the right.

• Set the following parameters in the Gravity window them click to save the settings
