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 ? |

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.
