18) We have defined the P flux
0 at X boundary. Now Proceed further to specify the boundary condition at remaining three faces.
19) For X+, Y+ we will apply same boundary condition as for X. So change only entire boundary to X+ and Y+ and click Apply every time.
20) For Y everything will remain same as above except the boundary condition type as Value and Entire boundary at Y. Click "Apply".
21) Click "Advanced.." on Initial & Boundary Conditions dialog window to reach Advanced Initial & Boundary Conditions dialog window (see Fig 2.5)
Fig  2.5: Advanced Initial & Boundary Conditions dialog
22) Click "Gravity >>". A dialog window appears. Here we will specify the normalized value of gravity. Enter the value as shown in fig 2.6 and click "Apply".

23) Close the Advanced Initial & Boundary Conditions dialog box by clicking on "Close".
This concludes the initial and boundary conditions for the problem in hand.
24) Click "Next" to go to the "Fluid Properties & Constants". For the present problem we will not specify anything from
this section.
25) Click "Next >" to reach "Solid Matrix Properties" dialog window as shown on fig 2.7
Fig  2.7: Solid Matrix Properties dialog window
26) Select "Hydraulic Properties >>" from Solid Matrix Properties dialog window and enter the values as follows
 Matrix Compressibility as 0.0.
 Hydraulic X components Kx as 0.00112 and Hydraulic components Ky as 0.00112.
 Click "Apply".
27) Now go to "Advanced" button available on Solid Matrix Properties dialog window. (See fig 2.8)
Fig  2.8: Advanced Solid Matrix Properties dialog.
28) Select "Property Interpretation >>". A dialog window appears. Choose the option as:
 Compute diffusion coefficient as Geometric mean of the two nearest grid node values.
 Select dependent variable as P.
 Click "Apply". (see fig 2.9)
Fig  2.9: Property Interpretation dialog window
29) Now go to "Multiphase Characteristics >>" option. A dialog window appears as shown in fig 3.0
Fig  3.0: Dialog window for multiphase characteristics.
30) Click "Saturation in terms of Capillary Pressure >>" and enter the value as:
 Select Saturation as "Exponential".
 Enter the value of empirical constants A and B as 1.0 and 0.1258 respectively. (see fig 3.1).
 Leave other values as default.
