Hello everyone,


I am simulatin an oven. The oven has two ducts inside. One that inyect hot air and one that extract the air. The oven is open to the environment in its ends.


The boundary conditions al inlet and outlet are in the ducts. However, i dont know the pressure value there. The only known value is in the ends of the oven, where is open to the environment (Patm).



I cant obtain good values of the pressure distribution when i run the simulation. The only value across all the domain is the internal field value.


I would like to know if some of you have a recommendation for my boundary conditions in order to improve my results.

dimensions      [1 -1 -2 0 0 0 0];

internalField   uniform 1e5;

boundaryField
{
    doorin
    {
        type            fixedValue;
        value           uniform 1e5;
    }
    doorout
    {
        type            fixedValue;
        value           uniform 1e5;
    }
    symmetry
    {
        type             symmetryPlane;
    }
    walls
    {
        type            zeroGradient;
    }
     box
    {
        type            zeroGradient;
    }
    inlet1
    {
        type            zeroGradient;
    }
    outlet1
    {
        type            zeroGradient;
    }
