Correlation functions for the added mass force.

To be compatible with the interface of AddedMassForceEvaluator, all functions use the following signature: Vector3<real_t> ( const Vector3<real_t> & timeDerivativeFluidVel, const Vector3<real_t> & timeDerivativeBodyVel, const real_t & bodyVolume, const real_t & fluidDensity )

Various correlation functions for the drag force.

These functions calculate the drag force for fluid-particle interactions based on different empirical correlations from literature. Always be aware that those empirical formulas were obtained by different setups and are thus not generally applicable!
