Hi Sushil,<br class="">
<br class="">
I do not know which file in your google drive is the one you used to make the plot, but I found some potential problems in a similar script yt_frb_offaxis.py:<br class="">
<br class="">
1. When you load the data, with data = dict(?), the key values should be ?velocity_x/y/z? instead of ?cutting_plane_velocity_x/y/z?, since the later can be derived from the velocity field you provided;<br class="">
<br class="">
2. The data for stream plot should not be normalized;<br class="">
<br class="">
Here I attached the script, and you should be able to produce the figure without problem.<br class="">
<br class="">
Best wishes,<br class="">

Hello yt users,<br class="">
<br class="">
I tried to use the LightRay class to generate a light ray for one of my gridded simulation snapshots. The simulation is from the FIRE project which used a heavily modified version of Gadget-3 called GIZMO written by Phil Hopkins. And the error I got is: ValueError: need more than 1 value to unpack.<br class="">

Hi Fei Li,<br class="">
<br class="">
Since you're primarily trying to use Trident's functionality which wraps<br class="">
around the LightRay class, you should probably direct questions of this<br class="">
nature to the Trident mailing list. I'll start a discussion there on this<br class="">
topic now and cc you.<br class="">
