Detailed Description

template<typename T>
class olb::EllipticPoiseuille3D< T >

This functor returns a quadratic Poiseuille profile for use with a pipe with elliptic cross-section.

Ellpise is orthogonal to z-direction. a is in x-direction b is in y-direction Velocity profile for util::round pipes.
