Integration Time

#1

Hi All,

I am curious about the “Integration Time” variable that is available after generating a vtkStreamline. I understand that this is some measure of the age of the streamline, but what are the units here, and how is this variable calculated? The values I get for seem to be too large to be in seconds, but maybe I am wrong about this.

The integration time is derived from the velocity computed by the vtkInterpolatedVelocityField:

The unit then depends on the unit of the Vectors in use for integration.
