在使用overPimpleDyMFoam计算旋转机械 时，出现了如下报错：

使用的动网格文件如下：
motionSolverLibs ("librigidBodyMeshMotion.so");
dynamicFvMesh dynamicOversetFvMesh;
motionSolver rigidBodyMotion;
// rigidBodyMotionCoeffs - not needed any more
// {

{

}

omega sine; // Function1 entry
omegaCoeffs
{
frequency 4;
amplitude 0.2;
scale (0 1 0);
level (0 1 0);
}
}
}
但是如果把动网格文件改为：
dynamicFvMesh dynamicOversetFvMesh;
dynamicOversetFvMeshCoeffs
{
// layerRelax 0.3;
}
solver multiSolidBodyMotionSolver;
multiSolidBodyMotionSolverCoeffs
{
rotor
{
solidBodyMotionFunction rotatingMotion;
rotatingMotionCoeffs
{
origin (0 0 0);
axis (0 0 1);
omega 1.08;
}
}
}
就可以正常计算了。请问这是哪里出现错误了，跪求各位大神解答。
