oke sir, but there are some problems. if i set material air is gas ideal. why i dont set operating condition pressure and spesific density?

[DrAmine]

you can set both even with ideal gas. For low mach numbers flows even very important to set operating pressure. For buoyancy related cases setting an operating density is also important to provide correct input on pressure boundaries

[mlutfiaziz32]

in notification if  i use ideal gas so density specific recommended velue Zero.

 

[DrAmine]

Ignore that notification. I recommend providing an operating density. I usually use zero but in certain cases and to facilitate setting up multicomponent cases and if the conditions outside are the same I usually provide the density of the outside as operating density.

sorry mr. abenhadj, do i must set pressure location???

[mlutfiaziz32]

in operating conditions

Hello,

You can leave the pressure location as default. That is alright.

As suggested by my colleague, please do set the operating density if you are working with buoyancy related flows. You could use the default value of the operating pressure in most flows.

Thanks.
