@kkanade, thank you for your response. I have done as you suggested and copy-pasted each line of code in an interactive Fluent session. I did not come across any errors when doing this. Also, the specified number of iterations were completed. I did, however, come across a solution to this problem. While the line ÔÇ£/solve/iterate 25 qÔÇØ works, to get the green checkmark to appear, the number of iterations must be set before this command. This can be done by adding the command /solve/set number-of-iterations 25 q. If the number of iterations specified in both of these commands is different, then the /solve/iterate command will overwrite the /solve/set number-of-iterations command. For example, in the code segment below, only 10 iterations would be completed.

Iteration code segment:
/solve/set number-of-iterations 25 q
/solve/iterate 10 q

I am able to open Fluent iteratively, run just the command: /solve/set number-of-iterations 25 q, then close Fluent, and the green checkmark will appear. It seems that the checkmark is only an indication that the number of iterations has been set and not if the calculations have been completed. Obviously, doing this will not allow you to move on to the post-processing step.
