Hi all, I am currently trying to develop a coupled solver. I am currently at the stage of coding the transfer of information between the 2 solvers. I am following the template setPressure.H due to the similarities.

{
    Info << "Setting " << endl;

    // interpolates the pressure from the fluid field to the
    // solid patches at the fluid-solid boundary
    scalarField solidPatchPressure =
        interpolatorFluidSolid.faceInterpolate
        (
            p.boundaryField()[fluidPatchID]
        );

    solidPatchPressure *= rhoFluid.value();

    // tforce is Reference for traction displacement BC
    tForce.pressure() = solidPatchPressure;

    // calculates total force from pressure
    vector totalPressureForce =
        sum
        (
            p.boundaryField()[fluidPatchID]*
            mesh.Sf().boundaryField()[fluidPatchID]
        );

     
    Info << "Total pressure force = " << totalPressureForce << endl;
}

Can anyone guide me on what has to be changed if I were to require the depth and velocity of shallowWaterFoam to be patched onto z(level) and velocity of interFoam?
