Dear Foamers,

i used buoyantBousiesqPimpleFoam to simulate a room ventilation. i defined B.C of inlet as temperature fixedValue 290K as seen below.

boundaryField
{
    wall
    {
        type            zeroGradient;
    }
    inlet
    {
        type            fixedValue;
        value           uniform 290;
    }
    windows
    {
        type            fixedValue;
        value           uniform 305;
    }
    door
    {
        type            fixedValue;
        value           uniform 300;
    }
}

After solving all grids have temperature of more than 300K
why is boundary fixed value changed?
