I am running an input file to ramp up the inlet pressure on a model. Each time I ramp up the pressure I allow the solution to converge and save the case, data and interpolation of the results. 

This works well for the most part, however if I do this multiple times in a row (overnight to get a range of results) fluent will sometimes fail while saving the data. The following error occurs: 

"Error: EOF in string readError Object: ()"

This stops fluent reading my journal file and the rest of the analysis is halted because of it. 

I have looked at the strings in question and there is no clear difference between that and any of the other strings fluent has previously read to save the data (one number changing each time). There are no '%' signs in any of the strings which seems to cause this error sometimes and I can't see anything that would produce an EOF error. 

I was wondering if anyone had similar issues or if there is a fix to this problem.

Are you running, saving, interpolating, running on, saving, interpolating, running on... etc? You may find the process RAM isn't freeing up completely so over time things go wrong: assuming there aren't any random "acts of IT" on the computer/network overnight. That's the drawback of running multiple cases through one solver session rather than running several solver sessions sequentially.
