  Hello, everyone.
  I used the overset grid of fluent, but the warning comes out "WARNING: sliding boundary zone 37 is in close proximity to active overset interface cells" during calculation. I increase the distance between zone 37 and overset component, and it doesn't work. Could someone help me?
  With best regards

  It's a warning https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v232/en/flu_ug/flu_ug_sec_overset.html so if the interface isn't interfering with the overset data transfer you should be OK. I don't know how the check is made, so you could find it's due to the distance relative to the domain scale.
