I am struggling to find the .H / .C files where the "transform" is used.

FoamFile
{
    format      ascii;
    class       dictionary;
    object      dynamicMeshDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

mover
{
    type            motionSolver;

    libs            ("librigidBodyMeshMotion.so");

    motionSolver       rigidBodyMotion;

    rigidBodyMotionCoeffs
    {   
        report          on;

        solver
        {
            type Newmark;
        }

        accelerationRelaxation 0.7;

        bodies
        {
            floatingObject
            {
                type            cuboid;
                parent          root;

                // Cuboid dimensions
                L               (0.1 0.1 0.1);

                // Density of the cuboid
                rho             800;

                // Cuboid mass
                mass            #calc "$rho*cmptProduct($<vector>L)";
                centreOfMass    (0 0.08 0.08);
                transform      (1 0 0 0 1 0 0 0 1) (0.4 0.45 0.35);

How should I proceed to find it (I tried banana but in this case it didn't help, and searching the API neither), for future reference ?

I got that it corresponds to the centre of rotation (geometrical centre of the floating object), and that it enables to place the centreofmass (given in local coordinates with 0 0 0 the centre of rotation) in the global coordinates system, but I really can't find the actual files where this is done in the C++ reference guide...

I think the good starting point for this would be the rigidBody library itself.

Particularly in your case, within

PHP Code:

$FOAM_SRC 


I can see there is a

PHP Code:

rigidBodyDynamics 


So if I look for "transform" here, I would be able to get the definition/declaration of transform.

PHP Code:

grep -nr "transform" . 


then one of the outputs would be:

PHP Code:

./rigidBodyModel/rigidBodyModel.C:201:                bodyDict.get<spatialTransform>("transform"), 


Hope this helps.
