hi all,

I am trying to run Fluent v14.5 on 16 cores and am having a problem.

Sometimes when I click cancel to interrupt the iterations, it stops as normal then around a second later Fluent disappears without any warning.

When I check the error log file it says:
"Error [node 999999] [time 7/23/13 12:21:41]".

Does anyone have any idea how I can fix this?

Any help would be greatly appreciated.

Phil

sorry I left out a bit at the end of the error message, the full message should read:

"Error [node 999999] [time 7/23/13 12:21:41] Abnormal Exit!"

any help would be hugely appreciated!!!

Although I am not sure but this may have something to do with node-master communication.

I also suggest you try different method for mesh partition for parallel calculations.

what do you mean with node-master communication??

The problem happens with the version 14.X, when I run the case with Fluent 12.X, there is no problem...

Before closing the window automatically, it shows "[...]fluent14.5.7\cortex\win64\cx1457.exe received fatal signal (ACCESS_VIOLATION)"


I tried to execute just the cx1457.exe, and it says that a dll file is missing, but it is actually there!!!

Any clue??

Thank you!

I am not a cluster geek but all I understand is this: if you dont have your MPI set right then there could be issues with communication between nodes.

The 'node 999999' error also has something to do with UDFs. If your UDF is not compiled with right program (32 bit-64 bit) or right way then there could be some issues.

If you using academic license then it also comes with some limitations e.g. no. of node that can be used for parallel process.

I'm thinking that problem may be due to the boundary conditions, even I tried changing the BCs. But still it is getting the same error and disappearing without giving any information. I'm not understanding what to with this..


"Error node [99999] Abnormal Exit"..

Any help would be appreciated...


Thanks,
Shivakumar

Try using a different MPI or playing with your MPI settings.

Hello;

I do not know exactly how to solve the problem you are facing: But i will share my experience of parallel fluent -

PBS File looks like:

### PBS ###
#PBS -l nodes=2 : ppn=8 ( Ok there is no space between : and ppn but I had to use it because a weird emoticon << keeps coming up)
#PBS -l walltime=30:00:00
#PBS -j oe
#PBS -o FILE.log
#PBS -V
#PBS -N Jobname
cd $PBS_O_WORKDIR
cd /home/usr [ This is where you are submitting your job from so figure it]
/data1/ansys/v150/fluent/bin/fluent 3ddp -i pressurebased.jou -t16 -g -mpi=openmpi -ssh >> logfile


OK So using these settings you can create the batch file. Now for the journal file make sure you have it saved in unix format: You can definitely create it in windows also, and transfer it to the linux system: Open the file using VIM editor ( that's what I use) and follow these commands:

:w ( write the file once more)
: set ff=unix ( set the file format as unix)
:wq ( write and quit the file)

hope it gets sorted now: if not come back and ask i will try to help

This is usually an intermitten problem with parallel FLuent and it's usually a problem with the MPI. Is your problem intermittent or does it always happen? Try using a different MPI or reconfiguring your current MPI.

hi,
I tried every settings which are discussed in this forum but couldn't solve it.
Finally, I Uninstalled ANSYS 14.0 and installed 15.0 version, the problem disappeared automatically.

Thanks,
shiv
