CFD Online Discussion Forums - forces and forceCoeffs script is not working properly with RBF solver

Hi Everyone,

I am trying to run the simulation for pitching and heaving motion for NACA0012 airfoil by using RBF motion solver in foam extend 4.0.

Whenever, I am using below force script in controlDict for simulation the airfoil behaves like static airfoil, I mean there is no pitching and heaving motion occurred (without this force script it seems fine but not able to get force data files).

I don't know, where am I doing wrong? Can someone please look into and guide/correct me?

PHP Code:


		
			
functions

{

    forces

    {

        type                       forces;

        functionObjectLibs   ( "libforces.so" );

        outputControl          timeStep;

        outputInterval         1;

        patches                  (airfoil);

        pName                   p;

        UName                   U;

        rhoName                rhoInf;

        log                         true;

        rhoInf                    997.07;

        CofR                      (0 0 0);

    }

    forceCoeffs

    {

         type                       forceCoeffs;

        functionObjectLibs   ( "libforces.so" );

        outputControl          timeStep;

        outputInterval         1;

        patches                  (airfoil);

        pName                   p;

        UName                  U;

        rhoName               rhoInf;

        log                        true;

        rhoInf                   997.07;

        liftDir                    (0 1 0);

        dragDir                 (1 0 0);

        CofR                     (0 0 0);

        pitchAxis               (0 0 0);

        magUInf               0.0179;

        lRef                      0.05;

        Aref                     0.05;

     }

}

Thanks

Best Regards
