This relates the rate of change of a quantity within an infinitesimal control fluid volume that we would witness if we were riding with it along a streamline (Lagrangian viewpoint), to the rate of change of the quantity that a stationary observer would witness from their vantage point on the streamline (Eulerian viewpoint).

2008: Most of the developments for this release are in: new applications, e.g. for multiphase flow and cavitation, buoyancy-flow and heat transfer, high speed flows and even molecular dynamics; new utilities, e.g. for meshing and case monitoring; and, new modelling, e.g. in Lagrangian particle tracking, radiation and rotating frames of reference.

Define the convective, total or material material derivative operator as


\frac{D}{Dt} = \frac{\partial}{\partial t} + \mathbf{U} \cdot \nabla

This relates the rate of change of a quantity within an infinitesimal control fluid volume that we would witness if we were riding with it along a streamline (Lagrangian viewpoint), to the rate of change of the quantity that a stationary observer would witness from their vantage point on the streamline (Eulerian viewpoint).
