This paper presents a novel method to extract vortical structures from
3D CFD vector field automatically. It discusses the underlying theory
and some aspects of the implementation. Making use of higher-order
derivatives, the method is able to locate bent vortices. In order to
structure the recognition procedure, we distinguish locating the core
line from calculating attributes of strength and quality. Results are
presented on several flow fields from the field of turbomachinery.
