Running Fluent on Cluster- clear Node Cache

      Hello,


       


      I am running models on a HPC cluster (Linux). I received the following warning.


       


      WARNING: Rank:44 Machine node002 has 13 % of RAM filled with file buffer caches.


      This can cause potential performance issues. Please use -cflush flag to flush the cache. 


      (In case of any trouble with that, try the TUI/Scheme command '(flush-cache)'.)


       


       


      I tried using -cflush on the node of the HPC and it says its an invalid command. I also tried 'flush-cache' in the Fluent console and it also said it is an invalid command. Where is the proper place to use this command?


       


      Thanks,


      Alex
