pressure in a enclosure
 

i want to set the initial pressure in a cylindrical cavity that is closed like capsule to 10 atm , in cfx-pre domain initialization static pressure with value i set the value to 10 , ref pressure to 0 , but at the solving stage i have warning that says no pressure value at domain node 1 pressure to 0 .
what should i do ?

Please post an image of what you are modelling and your CCL.

For simulations in enclosures use the "pressure level information" settings in advances options in solver control, and set the relative pressure to 0 bar. The solver will then compute all pressures relative to your reference pressure that you set in the basic settings.
