Why I encountered the spaacis/src:UNITS_NOT_EQUAL problem?

[fenfam]

I'm doing multiscale research, so usually the python scripts need to be executed many times, but it always show these like below,

????????
*** Warning (spaacis/src:UNITS_NOT_EQUAL)
save units not equal to the restored units
????????

When I rerun the scripts, it does not show these errors until the scripts are excuted several times, could any one provide some suggestions, thanks for any help.

 

[FEA way]

Do you get any additional error/warning messages in log files or just this one ?

I check the log file, it is always stucked in this line 'run standard.exe', then stopped to proceed .
I also try to manually stop the job with 'abaqus job=jobname terminate', it did not work and was still stucked in this line.
By the way, I was using MATLAB to system call these lines, so when it occurred , I had to 'ctrl + C' to stop the whole program and then rerun them.
Especially, dut to the force stop, if I delelete the current job temp files and rerun the abaqus python scripts, it could still work well, but I have to use these scripts in MATLAB parfor iterations, so manual control is not realistic.
