flotingObject case doesn't run when I change the dynamicMeshDict file.
 

Hi, Foamers! I have met an anxious problem. Please give me your hands.

I have changed the case of floatingObject in the OF-3.0.1. Firstly I define a box in the topoSetDict. And then I make some changes in the dynamicMeshDict. I use the solidBodyMotionFvMesh, and define a linearMotion function, like that
dynamicFvMesh solidBodyMotionFvMesh;
solidBodyMotionFvMeshCoeffs
{
cellSet c0;
solidBodyMotionFunction linearMotion;
linearMotionCoeffs
{
velocity (0.5 0.5 0);
}
}

But when I run the case, some error messages occur, the error information is
"--> FOAM FATAL ERROR: Illegal content 286695 of set:c0 of type cellSet Value should be between 0 and 286694"

And when i paraFoam the case, i see a terrible surface of floatingObject defined in the topoSetDict.

If i don't change the dynamicMeshDict, just like the tutorials in of-3.0.1, the case can be run well. And the floatingObject is normal.
