Hello,
I am having troubles with 'programming' on a function object of a solver that uses `basicKinematicCollidingCloud`. I have on my mesh a volumetric scalar field I, and I have particlesCloud which are basicKinematicCollidingCloud.
I wanted to use the coded function object, to:
1. recover the I field
2. recover the cloud
3. find the ID of the cell where each particle is located
4. save the evolution of the field I over each particle (so at each time step note the I where the particle is)
5. ideally extend it to make a linear interpolation between the center of the particle and the center of the location of cell center so it is more precise.

but I am struggling to recover the cloud field, I havent found much about using the lagrangian data in run time with exception of this posts:
Access particle data from functionObject
Lagrangian particloe Tracking and getting values back

what I have up to now:
the function object (if I uncomend any of the commends parts the compilation fails):

    fieldLagrangeanVol
    {
        libs            (utilityFunctionObjects);
        type            coded;
        name            fieldLagrangeanVol;
        writeControl    timeStep;
        writeInterval   10;
        // codeInclude
        // #{
        //     #include "basicKinematicCollidingCloud.H"
        // #};

        codeWrite
        #{
            const auto& banana = mesh().lookupObject<volScalarField>("banana");
            // const auto& t = mesh().lookupObject<basicKinematicCollidingCloud>("cellCloud");
            // const auto* t1 = mesh().findObject<cloud>("cellCloud");
        #};
    }

and the cellCloud is defined in the create field:

word cellCloudName("cellCloud");
basicKinematicCollidingCloud cellCloud
(
    cellCloudName,
    rhoInf,
    U,
    mu,
    g
);

I am getting the following errors while compiling (if I remove the commend from the corresponding line)
if I active t:
