I'm doing an exercise with a non-comformal periodic boundary condition. When I got a convergent solution at the creteria of 0.001 by default, I saved the case and the data. But the next time I loaded the same case and data, I found that the case was different from that I saved before! I didn't do any change on the case indeed.

In order to confirm my suspicion, I do the procedure as follow: 1. Reset the case and do the interation until it converged. 2. Save the case and the data. 3. Open another Fluent window, load the saved case and data. Now there are two Fluent windows in the system. 4. In both windows, do the initialization again, then both do the interation and observe both the redisual windows.

The result: I foundd that the redisual in the two windows were totally different. Furthermore, the original one converged, but the save-reload one didn't converge. Why cound this happen? Have somebody ever got this problem? How can I solve it?

hey ,

thats strange try with saving the case and data file in different name when you modify it and save it.

try using new files (with new file names)

Hi, I did as what you said, but it still no use. The data seems the same, but the case is not.
