I have a heated plate opened to atmosphere.
I am using buoyantBousinesqPimpleFOAM.
Mesh is four imaginary walls (open to atmosphere) and a roof (open to atmosphere) and a stationary floor with heated plate at centre.

My boundary conditions are as follows.


FoamFile
{
version 2.0;
format ascii;
class volVectorField;
object U;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [0 1 -1 0 0 0 0];

internalField uniform (0 0 0);

boundaryField
{
floor
{
type fixedValue;
value uniform (0 0 0);
}
heatedplate
{
type fixedValue;
value uniform (0 0 0);
}
inletwall
{
type pressureInletOutletVelocity;
value uniform (0 0 0);
}
roof
{
type inletOutlet;
inletValue uniform (0 0 0);
}

}

I just want to know if boundary conditions are correct.
Please let me know if there is a problem.
Also could anyone describe pressureinletoutletvelocity in layman terms!
Any help would be much appreciated.
