Hey everybody Hope you are doing great!

I wanted to write a program in which the initial and boundary conditions for the fields depend on some initial calculations.
At first, I thought it would be a good idea to write a C++ program that reads and edits the files in the 0 the folder; then I figured out it is not that easy; so I came to the conclusion that it might be best to try this method but I'm not quite sure yet:
I decided to define the fields in the main file. Is there any way to create a volVectorField or volScalarField in the .C file with defined boundary and initial condition? For example, I want to have something like this in my .C file:
Code:
/*--------------------------------*- C++ -*----------------------------------*\

\*---------------------------------------------------------------------------*/
FoamFile
{
    version     2.0;
    format      ascii;
    class       volScalarField;
    object      eps;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions      [0 0 0 0 0 0 0];

    inlet
    {
        type            zeroGradient;
    }
    outlet
    {
        type            zeroGradient;
    }
    fixedWalls
    {
        type            zeroGradient;
    }
}

I would be very appreciative If someone could help me with this!
