Hi Junhwan,
I would like to estimate the gas density profile between two points in the simulation. Let say the tow points are (x0, y0, z0) and (x1, y1, z1), and make line between them. This line will intersect with the grid cell and I would like to make profile of the density as function of the distance from (x0, y0, z0).

I think that I can use the ray object and make profile from this, but there is very limited information how to do so.
We're sorry! We'll make a note of this, and if you have any suggestions on how to improve them, let us know. Good luck! -- Stephen Skory s@skory.us http://stephenskory.com/ 510.621.3687 (google voice)
