[yt-users] Problem in simple volume rendering (yt-users Digest, Vol 36, Issue 18)

[Kuo-Chuan Pan]

Dear Matt,

Thank you so much for your help!
Changing the width to pf.domain_right_edge -pf.domain_left_edge seems works now!
but it is still calculating  (> 2hrs).

I thought width=1 refer to the whole domain.

After the calculation finished, I will let you know whether it works or not.
Thank you so much.

Best,
Kuo-Chuan
