38) Go to "CONVERGENCE CRITERIA >>". We will use the following variables for convergence monitoring;

    1. Select U as the convergence variable.
    2. Check use as reference variable checkbox.
    3. Check Global residual.
    4. Enter the value 1.0E-07 as epsilon. (see fig 2.9)
    5. Enter 10 for maximum number of inner iterations.
    6. Click "Apply".

    2. Fig - 2.9: Convergence dialog window

    1. Select V as the convergence variable.
    2. Uncheck use as reference variable checkbox.
    3. Check Global residual.
    4. Enter the value 1.0E-07 as epsilon.
    5. Enter 10 for maximum number of inner iterations.
    6. Click "Apply".

  3. Now Select W as convergence variable and everything will remain same as for V. Click "Apply".

  4. Select P as convergence variable. Change only Maximum number of iteration to 50 and Click "Apply".

  5. Select K as the convergence variable. Change only the value of epsilon to 1.0E-06 and Maximum number of iteration to 10 and other things will remain same as for V. Click "Apply".

  6. Select E as the convergence variable. Change only the value of epsilon to 1.0E-05 and Maximum number of iteration to 10 and other things will remain same as forV. Click "Apply".

39) Now click "Advanced". A dialog window appears. ( See Fig 3.0)

40)Go to "Relaxation Factors >>". A dialog appears (see fig 3.1)

Fig 3.1 Dialog window for Relaxation Factor

  1. Choose relaxation factor for U, V, W, P, K, E, L and MU as 0.2, 0.2, 0.2, 0.6, 0.2, 0.2 and 0.2 respectively.

  2. Click "Apply".

41) Close the Advanced Operational Control dialog window by clicking "Close".

42) Click "Next >" to go to Runtime Control dialog window. (see Fig 3.2)

Fig 3.2 Runtime Control Dialog Window

43) Click "Solve >>" and dialog box appears as shown in fig 3.3

  1. Choose Customize "SOLVE" Command Options under solution Options.

    2. Fig 3.3 Steady State dialog box

  2. Specify Maximum and Minimum number of steps as 1000 both, for fixed number of steps.

  3. Click "Apply".

44) Click "Finish" and message window will appear as shown in fig 3.4a.
