Hello!

I'm trying to simulate a case using rigidBodyMotion but following error shows up before the case runnning even though rho is set in dynamicMeshDict. I'm wondering if someone has experienced this error before.

-------------------------------------------------------------------------------
[24] --> FOAM FATAL ERROR:
[24] Could not find rho:rho
[24]
[24] From function void Foam::functionObjects::forces::initialise()
[24] in file forces/forces.C at line [25]
--------------------------------------------------------------------------------

I also tried use forces function object like DTCHull tutorial but that doesn't work either.
Here is my dynamicMeshDict.

dynamicFvMesh      dynamicMotionSolverFvMesh;

motionSolverLibs ("librigidBodyMeshMotion.so");


solver             rigidBodyMotion;

rigidBodyMotionCoeffs
{
        report  on;

        solver
        {
                type    CrankNicolson;
        }

        accelerationRelaxation  0.9;

 bodies
        {
                movingwall
                {
                        type    rigidBody;
                        parent  root;

                        mass            0.05;
                        centreOfMass    (0 0 0);
                        inertia         (5e-10 0 0 2e-9 0  2e-9);            
                        rho            rhoInf;
                        rhoInf                  1200; 
                        transform     (1 0 0 0 1 0 0 0 1)(0 0 0);

                        joint
                        {
                                type    composite;
                                joints
                                (
                                        {
                                                type    Py;
                                        }
                                        {
                                                type    Ry;
                                        }
                                );
                        }

                        patches         (movingwall);
                        innerDistance   0.5;
                        outerDistance   1;
                }
        }
}

I use OpenFOAMv1612 here.
I would appreciate if someone gives me advise.

Thank you!

For anyone stumbling on this, the rho declarations are in the wrong spot, and belong one level up for example below the "report on;"
