Hi John, Sam might know better than I do, but if you've extracted them to AMRStreamline objects you can access the field 'dt' to get path length through every zone. -Matt On Fri, Dec 2, 2011 at 2:32 PM, John ZuHone <jzuhone@milkyway.gsfc.nasa.gov> wrote:

Hi all,

Does anyone know how to get an arc length out of the streamlines? t is dimensionless but must be related to it somehow.

Best,
