“…If the governing equations are expressed in terms of these coordinates, they can be solved inversely to produce a curvilinear coordinate system which defines the flow. This approach has been used to solve extrusion flows (Clermont and De La Lande 1993, Greywall 1993, Greywall and Bolleddu 1996 and axisymmetric vortex flows in ducts (Keller 1996). Unfortunately, once a flow exhibits a swirl, one of the stream functions becomes multivalued and, so far, a successful strategy for dealing with this has not been found.…”

A review of CFD visualisation methods together with policy statements by visualisation experts conclude that the visualisation of complex 3D and 4D CFD data fields is still a major research challenge. Potential methodologies are discussed and it is suggested that a suitable approach and target for research is to understand how derived scalar and vector fields, such as dual stream functions and the Lamb vector, relate to the structure and physical characteristics of a flow. A particular focus is to use these fields to generate 'structural' stream functions with isosurfaces that divide the flow into self contained regions.
