30) To specify Initial Conditions Select First Dependent VariableU from the list.
- Keep the Replace previously specified condition (if any) item checked as the type of initial condition.
- Keep the Apply to item at Entire Domain.
Note: Since we will be setting the condition as a constant, Select independent variable item is insignificant.
- Check Constant and enter the value 1.0.
- Click "Apply".
31) Click upon Initial Conditions Tab again and enter Dependent variables specifications for P, K and E one by one. Thus Set V=0.0: Change only the dependent variable to V and the constant value to 0.0, click "Apply".
32) Set P=0.0: Change only the dependent variable to P and the constant value to 0.0, click "Apply".
33) Set K=0.01: Change only the dependent variable to K and the constant value to 0.01, click "Apply".
34) Set E=0.111: Change only the dependent variable to E and the constant value to 0.111, click "Apply".
That concludes the setting of initial conditions.
35) Click "Boundary Conditions >>" button. This screen is shown in Fig.2.9. We will provide the experimental inlet values of U and K as a constant value.

Fig - 2.9: Window for specifying the boundary conditions for U Variable
36) For U values at the inlet
- Select U as the dependent variable;
- Leave type of boundary condition at Value;
- Click on "Entire Boundary"
- Select X- as direction;
- Select Y as the independent variable
- Select Constant and enter the value in text field as 1.0.
- Click "Apply".
37) Similarly Set K=0.01: Change only the dependent variable to K and the constant value to 0.01, click Apply".
This concludes the boundary conditions
38) Click "Next >" to go to FLUID PROPERTIES & CONSTANTS dialog window. Here we will specify the fluid density and viscosity.
39) Click "Density >>" to go to Set Fluid Density dialog window as shown in fig 3.0
- Select Constant Density and enter the value as 1.0.

Fig - 3.0: Dialog window for density
- Click "Apply".
40) Click "Viscosity >>" to go to dialog window for viscosity.
- Enter the Molecular Viscosity as 1.53E-03.

Fig - 3.0: Dialog window for Viscosity
- Click "Apply".
This conclude fluid Properties & Constants.
41) Click "Next >" to go to NATURE OF FLOW dialog window (See fig 3.1), and then select the options as follows. Click upon "Turbulence".

Fig - 3.1: Nature of Flow
- Select Turbulent, High Re Models then K-epsilon model as shown in fig. 3.2

Fig - 3.2: Window for to specify Nature of flow.
- Click "Apply"
42) Click "Next >" button to go to Output Option dialog window. (see fig 3.3)
