Detailed Description

template<typename T, typename DESCRIPTOR>
class olb::RotatingForceField3D< T, DESCRIPTOR >

This functor gives a parabolic profile for a given point x as it computes the distance between x and the axis.

The forces set are the fake forces caused by a non-Galilean frame, here rotating around an axis with a pulse w. There are:

The centrifuge force F = rho * w * w * (x-hx, y-hy, z-hz) | where (hx, hy, hz) is the projection of the point on the axis.
The coriolis force F = -2 * rho * w * (vx, vy, vz)°(Dx, Dy, Dz) | where ° is the vector product and (Dx, Dy, Dz) is the direction vector of the axis normed to 1 (named axisDirection in the code)

The boolean terms enable to choose having centrifugue or coriolis forces too or not. Functor for the rotation of forces.
