I am running my Fluent case on a HPC linux server in batch mode. I am using the following line in my .sh script file to include graphics in Fluent. 

fluent 3ddp -nogui -gu -driver null -t $SLURM_NTASKS -cnf=$NODEFILE -mpi=intel -pinfiniband -sifile=./"$SLURM_JOBID"_fluentServer2.txt -i $ansysFile.jou > kinetics_model_reacting.txt

The -gu -driver null options should enable me to create and save animations on the cluster. However, I am unable to do this. I am creating animations and changing their frequency using the following TUI commands. I have verified that the TUI commands are correct by inputting them in my local case setup.

/solve/animate/objects/create temp-animation_dist animate-on core_temp storage-dir "." q   ; creating animations on the contour named "core_temp"

/solve/animate/objects/edit temp-animation_dist frequency 200 q  ; change the frequency of writing files

Note that I am able to output animations if I had already set them up in my local case file. However, I am unable to set up new animations on the cluster.

Hello 

Is it throwing any error while creating animations with this TUI commands?

Hi, 

 

Ansys throws the following error and does not save the animation.

 

The contour which I am trying to animate does not contain any nan values. The contour represents a scalar field (see contour below).

Could you please also share the transcript to understand the error?

Hi,

I don't understand what you mean by transcript. Do you want the output file or do you want the journal file?

The output file throws the error that I showed above.

[Rahul]

yes, the content of output file.
