warning: for compressible (ideal and real) gas models with buoyancy,

 it is recommended to use a specified operating density value of zero.

 GUI access: Cell Zone/Boundary Conditions -> Operating Conditions... 

 TUI access: define operating-conditions operating-density

請問壇友，我仿真中的空氣通過鼓風機吹出，想設置成ideal gas，但是fluent出現以上警告（并非彈窗，只是在右下欄出現的提示）

這個意思是說要我把這里--specified operating density設置成0嗎？

謝謝！
