Re: how to stop FLUENT batch job and save the resu
 
There are two checkpointing modes:

* check-fluent - After the current iteration is complete, Fluent will save the current solution to case and data files, then continue running. * exit-fluent - After the current iteration is complete, Fluent will save the current solution to case and data files, then exit.

To do this on a UNIX machine:

* Create a text file with either the filename "check-fluent" or "exit-fluent" and place this file in the directory /tmp. The contents of the file are irrelevant - Fluent will only check to see if a file with one of the above names exists in the /tmp directory.

To do this on a PC/Windows machine:

* Create a text file with either the filename "check-fluent.txt" or "exit-fluent.txt" and place this file in the directory C:\TEMP. The contents of the file are irrelevant - Fluent will only check to see if a file with one of the above names exists in the C:\TEMP directory.

Notes:

* DOS requires the .txt extension on the filename. * Once a check-fluent or exit-fluent is performed, Fluent will automatically remove the file from /tmp or C:\TEMP. Thus, if you wish to perform another check-fluent, simply create a new file. * Fluent will append the current iteration counter to the filename so that unique filenames will be created if multiple instances of check-fluent are performed.

thanks a lot! i finally solve the problem!

i write my .jou as follow:

;case 1)save and exit (set! checkpoint/exit-filename "your directory.txt") ;case 2)save and continue (set! checkpoint/check-filename "your directory.txt") ... and type

touch your directory.txt

the process will case 1)stop,and Fluent save the .cas.gz and .dat.gz file,then exit.

case 2)stop,and Fluent save the .cas.gz and .dat.gz file,then continue the iteration.

thanks for you guys' help!
