Hi Foamers,

I'm fresh man in OpenFoam.
When I try to adding the temperature field into an 1/12 cylinder mesh, the problems occuring.

The following picture is my mesh:
In the right side is inlet, letf side is outlet. the other sides are wall. The middle one is ggi interface.

Here's my p:

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

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

internalField   uniform 0.98e5;

boundaryField
{
    OF_inlet_00
    {
        //type            zeroGradient;
        type            fixedValue;
        value           uniform 1.0e5;
   }
    OF_outlet_00
    {
        type            ggi;
    }
    OF_wall_00
    {
        type            cyclicGgi;
    }

When I run rhoSimpleFoam, the temperature and the pressure always increase crazy.
May I ask how to choose a suitable boundary condition for the simulation case?

Could you please point me out of the question?
Thanks a lot in advance.
