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
