Mixing Elbow

Important
Note that the ANSYS FLUENT settings file (FFF.set) is written before the
calculation begins.
Important
Note that while the program is calculating the solution, the states of the
Setup and Solution cells in the fluid flow ANSYS FLUENT analysis system in
ANSYS Workbench are changing. For example:
• The state of the Setup cell becomes Up-to-Date and the state of the Solution
cell becomes Refresh Required after the Run Calculation task page is visited
and the number of iterations is specified.
• The state of the Solution cell is Update Required while iterations are taking
place.
• The state of the Solution cell is Up-to-Date when the specified number of iterations
are complete (or if convergence is reached).
Note
As the calculation progresses, the surface monitor history will be plotted in the
graphics window (Figure 1.19 (p. 47)).
Note
The solution will be stopped by ANSYS FLUENT when the residuals reach their
specified values or after 300 iterations. The exact number of iterations will vary
depending on the platform being used. An Information dialog box will open to
alert you that the calculation is complete. Click OK in the Information dialog box
to proceed.
Because the residual values vary slightly by platform, the plot that appears on
your screen may not be exactly the same as the one shown here.
