OK good, the velocity fields have interesting patterns, even for the simplest case of a static electric field or gravitational field.

I will look into this tonight, we have a meeting of the Munich group today.

This is a particular solution of Note 356(4), using the assumption (1), that the components of the velocity field v in spherical polar coordinates are independent variables. This gives the non linear partial differential equation (7) and Eqs. (5) and (6) for the phi and theta components. The same analysis applies to the gravitational field g, which sets up a velocity field in spacetime.
