Fluent bandwitdh decrease in cluster

      Hi guys,

      I have a 6 nodes cluster and I use it to run ANSYS fluent. I found a wired problem. Everytime I reboot the cluster at the beginning, if I click parallel-bandwitdh, it behaves well, it shows around 4000m/s (max and min). But after I close/open fluent several times. It decrease, the more time I open/close flunet, the lower value it is. The minimux value is even 300m/s, average is around 1000m/s. It also has a very bad effect on the computation speed. I dont know why. Any suggestions?

      I am uing Fluent GUI to work. Thanks.

      Hello Kevin,
      You might want to clear out the cache, that might be causing the slowdown.
