Typedef Documentation

typedef std::vector<SamplePoint> Streamline

Stremlines are collections of SamplePoints.

Definition at line 162 of file streamlines.h.

Enumeration Type Documentation

enum SLIterAlg

Enumeration of available integration methods.

Enumerator:

ITER_RK	Runel-Kutter Integration (more accurate than Euler).
ITER_EULER	Euler Integration (a little bit faster tha Runel-Kutter).
