Detailed Description

template<typename T>
class olb::RotatingQuadratic1D< T >

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

This field is a scalar field, a vector with one component will be used Functor with a parabolic profile e.g. for rotating pressure fields.
