As we already uploaded the files to create the region so here we will leave "Create New Region" option as we don't have any region to create now.

13) Either Click Next or Select the "Pre-Defined Boundary Types" option. (See fig 1.7)

Fig - 1.7: Pre-Defined Boundary Type.

14) Click on "Inlets >>" button on "Pre-Defined Boundary Types" dialog window.

1. Select the Region as "INLP".
2. Click "Apply".

15) Click on "Outlets >>" button on "Pre-Defined Boundary Types" dialog window.

1. Select the Entire Region as "OUTP".
2. Choose flow fraction 1.0.
3. Click "Apply".

16) Click on "Walls >>".

1. Click "Walls at all unspecified".
2. Click "Apply".

This concludes the PRE-DEFINED BOUNDARY TYPES specification.

17) Click "Next >" to go to INITIAL & BOUNDARY CONDITIONS screen. (See Fig. 1.8)

Fig - 1.8: Window for Initial & Boundary Conditions

18) Click "Initial conditions >>" to specify the initial guesses for the primary dependent variables. A dialog Window (See Fig. 1.9) will appear where we can set the initial guess for U, V, W, P, K and L.

Fig - 1.9: Initial Conditions screen for Dependent Variable U.

19) Set U=1.0E-06:

1. Select U from the Select Dependent Variable list.
2. Keep the Replace previously specified condition (if any) item checked as the type of initial condition.
3. Keep the Apply to item at Entire Domain. Since we will be setting the condition as a constant, Select independent variable item is insignificant.
4. Check Constant and enter the value 1.0E-06.
5. Click "Apply".

Revisit Initial Conditions Dialog to enter specifications for other Dependent Variables.

20) Set V=1.0E-06: Change only the dependent variable to V and the constant value to 1.0E-06, click "Apply".

21) Set W=1.0E-06: Change only the dependent variable to W and the constant value to 1.0E-06, click "Apply".

22) Set P=1.0E-08: Change only the dependent variable to P and the constant value to 1.0E-08, click "Apply".

23) Set K=0.1: Change only the dependent variable to K and the constant value to 0.1, click "Apply".

24) Set L=0.01: Change only the dependent variable to L and the constant value to 0.01, click "Apply".

That concludes the setting of initial conditions.

25) Click on "Boundary Condition >>" to specify the boundary condition. The upcoming dialog will be as shown in Fig.2.0.

Fig.2.0 Boundary Conditions screen For Dependent Variable U.

26) To set U values at the inlet select the options as:

1. Select U as the Dependent Variable.
2. Leave type of boundary condition at Value.
3. Click on "Region" as INLP.
4. Choose "Constant" as 10.0.
5. Click "Apply".

27)Set K=0.1; Change only the Dependent Variable to K and the constant value to 0.1, click "Apply".

28) Set L=0.01: Change only the Dependent Variable to L and the constant value to 0.01, click "Apply".

This concludes the boundary conditions

29) Click "Next >" to go to FLUID PROPERTIES & CONSTANTS dialog window.

1. Click "Density >>" to go to Set fluid Density dialog window.
2. Enter the value as shown in fig 2.1



Fig 2.1 Dialog window for density

3. Click "Apply"
4. Click "Viscosity >>" to go to Set Fluid Viscosity dialog window.
5. Enter the value as shown in fig 2.2.



Fig 2.2 Dialog window for Viscosity

6. Click "Apply".

This conclude fluid Properties & Constants.
