Linux parralel command line auto-save problem.
 
Hi,all, My problem is that when I use auto-save function in command line but fluent didn't save any file at all. When I use the command line to do fluent parralel under linux system. I have a.cas and a.dat files in my folder /public/. Below is my command line inputfile:

chdir /public/ /file/read-case-dat a.cas /solve/set/time-step 0.01 /file/autosave/data-frequency 200 /file/autosave/case-frequency 0 /file/autosave/root-name a it 1000 /file/write-data a.dat exit yes

But the fluent didn't save files something like a-200.dat. Anyone coule help me?

Thanks a lot.

Joe

Re: Linux parralel command line auto-save problem.
 
sorry for the bad format of script, here is the right format.

chdir /public/

/file/read-case-dat a.cas

/solve/set/time-step 0.01

/file/autosave/data-frequency 200

/file/autosave/case-frequency 0

/file/autosave/root-name a

it 1000

/file/write-data a.dat

exit

yes

please help to let me know where is wrong.

Thanks.

Try this format for the file name:

foo-%t.dat

the %t descriptor should add the time step at your file name.

I got it.

I should use "/solve/dual-time-iterate 1000 20" to replace "it 1000" here because my model is unsteady. But "it 1000" is for steady interation. so "it 1000" havn't make any one time-step.

thanks cfd-newbie, I try but no use.

This is not anything related to parallel. Just refer to the manual or contact a FLUENT support for help.
