Computes Lamb vector, i.e. the cross product of vorticity and velocity. Calculation of the divergence of the Lamb vector can be performed by using div function object on this LambVector function object.
The motivation of the function object is the literature-reported quantitative connection between the Lamb vector (divergence) and the spatially localised instantaneous fluid motions, e.g. high- and low-momentum fluid parcels, which possess considerable level of capacity to affect the rate of change of momentum, and to generate forces such as drag.
