Hello guys,
I am trying to assign alpha1 values to a variable A in compressibleInterFoam solver.
So I added a subroutine in createFields.H like this


Code:
volScalarField A
    (
    IOobject
        (
         "A",
         mesh.time().timeName(),
         mesh,
         IOobject::MUST_READ,
         IOobject::AUTO_WRITE
        ),
        mesh,
      dimensionedScalar("zero", dimless, 0.0)  
    );
A.ref() = mixture.alpha1();
But I could see alpha1 at first time step only. Later field is disappearing for remaining time steps.
Can anyone help me with this?

Hi Hari,

Can u see this new field in your intermediate time folders ? If yes, then something might be wrong with the OpenFOAM plugin of paraview. As an alternative try loading files via foamToVTK and then it should work.

Just Execute
Code:
foamToVTK
command in the home folder (where u hav your 0/ constant/ & system/ directory) ...this will by default write all the fields at all the time steps....open paraview (by
Code:
paraview
command) instead of paraFoam (as the issue might be from the FOAM's plugin of paaraview). Now File > Open > choose supported format - legacy VTK format....and then open the YOUR_TEST_CASE.vtk file

Hello shubam,
I am attaching a pic so that u can see what's actually my problem is?
ALPHA1 which I named as "A" is staying the same through out the runtime.
Thanks for the reply
