Scalar value along streamlines
 

Hello,

I would like to write in a file the x,y and z locations of a particle flowing along a streamline and the value of a scalar associated with its location at this position. With particles tracking it is possible to get its location, its velocity and temperature but nothing else. However particles can be colored by, for instance, the local concentration in O2 or anytihing else.

Thanks,

Yannick
