How to store a field in a new varianle and see it in paraFoam?
 
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.

Hello shubham,
Can you tell me How to load these files to vtk?
Thanks for your reply

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
