Reason for error: failed to connect to all addresses

[etiennelame]

I recently using pyfluent for calculation. The case worked well at the begining, but once the calculation timestep reached 722, the process broke and the python console show error of failed to connect to all addresses. At the beginning, I tried some method with ip address and tried reinstall the ANSYS, it did not work.

And then, I checked my problem case and found that it was ridiculously slow, even I replace with a mesh of 80000 cell, it was still ridiculously slow. But if I create a new case with the 80000-cell mesh, it can solve quickly.

Accidently, I write out the setting file with TUI command file/w-s resi. In the setting file, I found numberous of data was recorded in the rp-variables residuals/settings-transient and residuals/settings. After deleting the data of these two rp-variables in setting file, and re-read the setting file, the problem case worked well again.

I think that the reason for the problem is that: the case kept storing data into the rp-variables residuals/settings-transient and residuals/settings, too much data can slow down the process and maybe raise some error in Fluent and shut it down, then the pyfluent show the error code.

This is the setting file with problem. If anyone had idea to avoid this problem, please share the method and I appreciate your kindness
