Actually, I wrote some code in the jou. file, but I just can't get the picture. And I don't know the reason. nn

If you're setting the case up then running it I'd set the execute commands etc before running. Other than a few missing / at the beginning of commands that looks OK. When you run on the cluster are you running interactive or in batch? n

[DrAmine]

if you are running in batch: which command are you using to launch the fluent run? Moreover from your journal it seems that you are still using legacy contour plots: which version are you u using?n

Here is my run fluent file, this version is ansys 2020r1, I guess the reason could be this run_flueny file doesn't use graphics in cluster？ nn

[DrAmine]

To save pictures you need to run with the flags -gu -driver null (as mentioned in the documentation).n

I'm still confused, could you explain further? should I put this command in the run_fluent file? Where should I put? and which documentation? I have seen your shared link, I have looked it before, but it useless.n

Hi Array As Dr. Amine indicated, you need to launch fluent with -gu (to run without the GUI only, and not just -g since this turns off both graphics & GUI )nn

Thank you for your reply and example. I will try your advice in my jou. filenMay I ask in the 'run_fluent' file, should we also add some command to let the cluster know this simulation need ues GPU nodes? like the command in the figure (although this is not for GPU nodes)nn

[ai0013]

Well, I have no experience with gpus, but I guess you should use the flag -gpgpu=. If you mean number of processors, then you are doing it correctly, the flag is -t96 in your case, which is well replaced by -t$nprocsn

[DrAmine]

please check the documentation: it does answer all of your questions: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v211/en/flu_ug/flu_ug_sec_startup_option.html. All flags are mentioned there.n
