Dear foamers,

Recently, I am dealing with the dynamic mesh using Frank Bos' RBF code.
I am facing the problem of applying my kinetic model.
In my case the rotation frequency is changing with time. Therefore, I applied a function to the rotation matrix.

Now, I have few questions.
First, what is the meaning of this

vectorField rotationField
    (
        (RzCur - RzOld)
      & (statPoints_ - initialRotationOrigin_)
    );

Second, if the motion is equal to translationVector + rotationField, is it means the "motion" in the code is refer to a vector?

Many thanks,
Lida
