using rotatingWallVelocity in openfoam
 

i have made a case using rotatingWallVelocity it is running wellbut after some time i wish to stop the rotation.My boundary conditions are as follows.

}

inlet1
{
type fluxCorrectedVelocity;
value uniform (0 0 0);
}
inlet2
{
type fluxCorrectedVelocity;
value uniform (0 0 0);
}


defaultFaces
{
type empty;
}
}


// ************************************************** *********************** //

I am not able to stop the rotation since in the later time directories my boundary automatically changes to

inner_rotating_wall
{
type calculated;
value uniform (0 0 0);
}

Will changing the 0 time directory boundary condition will do the job ????
