Hello,

  I am running a Fluent (v241) in Linux and I read some articles about the optimization of Fluent. In one parametre, it suggests that run Fluent with option -platform=intel will increase the efficiency. As far as I know, Fluent can be run in two ways: Fluent launcher and command lines. Therefore, it's wrong when I type "-platform=intel" using Fluent launcher. Also, fluent24 -platform=intel is also wrong since the it will turn Secton Parallel Setting - Interconnects into intel, which obviously is wrong.

And I will appreciate it if anyone would help how to run Fluent with the optimization option -platform=intel in Fluent launcher or command lines (Fluent launcher is much better if it can be achieved)

BTW, the environment is : alias fluent24=$ANSYS2024_ROOT/fluent/bin/fluent

Hi 

Given your alias fluent24=$ANSYS2024_ROOT/fluent/bin/fluent, the correct command line syntax to launch Fluent with the AVX2 optimized binary should be: fluent24 -platform=intel

If you intend to run in parallel mode, you would also specify the number of processors using the -t option. Combining this with the platform option, the syntax would be: fluent24 -tX -platform=intel, where X is the desired number of processors.

Your observation that running fluent24 -platform=intel seems "wrong" or might affect the interconnect settings is noted. The Fluent user guide does not indicate that -platform=intel would change the interconnect type displayed or used by Fluent.

Hello,

   I try it and it turns wrong as I say and I record a video. I think the problem is that $ANSYS2024_ROOT/fluent/bin/fluent should point to the Fluent Launcher or command line mode of Fluent. In my environment, I want to use it within the Fluent Launcher(GUI mode). Therefore, which path of Fluent should I pointed to?
