I have used yt to determine the flux calculation for a region surrounding a
single star with a given mass loss rate. This region is right outside the
stellar radius (see attached). Comparing the flux calculation to the known
mass loss rate, I see that not all of the mass is accounted for and, what's
more, improved refinement of the simulation enhances this percentage,
however it is still below 70%. I need to calculate the flux for a region
surrounding a large group of stars, so simply increasing the refinement is
really not an option. Any suggestions as to how I can use yt for my flux
diagnostics in a manner that is more accurate?
Best,
Melinda
Hi!
I wrote a while back asking to visualize a dataset in an unstructured grid
with AMR and a vtk output file. I was given a script that could do simple visualizations: http://paste.yt-project.org/show/4879/ .
I tried altering it in order to visualize my data but (line 39), the number of elements in my vals array is odd, making the reshape become an error. Is there a way around it?
Thank you very much

Hello,
So I have flash code which generates data into polar coordinates and I need
to graph this data in polar coordinates with yt as well, but yt is
converting into cartesian coordinates. How can I fix this?
Hi All,
Is there a way to drop the units for a value in yt 3.0? For example, in
astropy, you can get the raw value of x (without units) by accessing
x.value.
Thanks,
desika
Has anyone tried taking the triangles output from yt's surface function and
plot them using Mayavi mlab? The 3d support in matplotlib is a bit
limited, so I was hoping to work in mayavi.

Hi All,
I’m new to yt’s mapserver function.
I’m trying this feature with a sample FLASH data which I got from data hub on my current yt (2.6 version).
However, error message came out like the following.
And when I used browser to connect to http://127.0.0.1:8080/, I got nothing.
Is there anything that I did it in wrong way? Any suggestion is welcome.
Thank you in advance.
Many thanks,
Jia-Hung Wu

Dear yt users,
I was trying to generate a FITS file from one of my simulations but I obtained an error I
do not understand and do not know how to solve. I followed the procedure in:
http://yt-project.org/docs/dev-3.0/visualizing/writing_fits_images.html
and in the moment I call fib = FITSImageBuffer(cvg, fields=["density"])
I obtain the error:
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)

--> 106 hdu = pyfits.PrimaryHDU(np.array(img_data[key]))
107 first = False
108 else:
AttributeError: 'NoneType' object has no attribute 'PrimaryHDU'
Any idea how can I solve this ?
thanks in advance
Juan

Hi All,
I'm having trouble reading Active Particle data from Enzo-3.0 outputs.
.
.
.
dd = pf.h.all_data()
print dd["RadiationParticle", "particle_position_x"]
.
.
gives
File "PrintActiveParticleInfo.py", line 18, in <module>
print dd["RadiationParticle", "particle_position_x"]

KeyError: ('RadiationParticle', 'particle_position_x')
>From dumping the hdf5 file the dataset (particle_position_x) exists in the

I'm probably missing something simple.... but any hints would be
appreciated!
Oh I'm using yt-2.7.dev
John
P.S.
Is there documentation on the yt website for reading Enzo-3.0 outputs?

Looking at the documentation for the PhasePlot here:
http://yt-project.org/docs/dev-3.0/visualizing/plots.html#d-phase-plots
both of the examples use "weight_field=None", but I think that for the
second case, we really want to omit that argument to get an average.
Looking at that plot, if we say that is an average, is seems strange to
have an H fraction of 100.
Am I missing something?

I am trying to use ortho_ray.
If I do:
c = ds.find_max("temperature")
coords = c[1]
ray = ds.ortho_ray(0, (coords[1], coords[2]))
and then plot ray["density"] vs. ray["x"] , I get a jumbled mess. Printing
ray["x"], I see that it is not monotonic -- should I expect it to be? The
docs seem to suggest that it would be sorted properly.
