[FLASH-USERS] Problem using VisIt

[Youngjun LEE]

Hi.
I solved that issue with directly edit the extract_ray.py script. Po-Yu
Chang(pchang at lle.rochester.edu) had helped me to solve that issue.

In extract_ray.py script, edit two lines just like this

[line# 20]  wl = t.getWhereList("name == n")   =>   wl =
t.getWhereList("name ==
'nstep
' ")
[line# 29]  wl = t.getWhereList("name == n")   =>   wl =
t.getWhereList("name == 'time
' ")

Please check there are several "spaces" after the string(nstep, time). This
is because the length of the string in the hdf5 file is 80.

Best,
