  Hi All,
  I should only use water as a fluid in my system. I have copied it from the fluent data base since the default is air, but I'm finding difficulties in deleting the air and it tells me it is been in use. I have alraedy checked the cell zone condition and the boundary conditions and no air in there at all but i'm just curious why i still can not delete it and where are other places i should check for the air ?
  I am using 2023R1, is it like i can not delete it at all in this version? please feed me back and thanks in advance
