Dear yt
Can current yt calculate 3-D Mass power spectra? I checked the website but
I didn't find any information. I think calculating 3-D Mass power
spectra is a very useful for cosmological simulations. So I guess maybe yt
supports this function now....?
Thanks in advance
Dear yt:
Is there a way to annotate sphere to a plot? I used annotate_sphere but it
plots an outline of a circle but I would like a "filled circle" to
represent a star?
I have a python script (see below) to create a sphere, but not sure how to
integrate it with yt
Any suggestions
Thank you in advance
#--------------------------------------------------------------------------
def create_sphere_coords(radius=10):
"""
function just returns a set of x,y,z coordinates for generating
a sphere.
"""
r = radius
pi = np.pi
cos = np.cos
sin = np.sin
phi, theta = np.mgrid[0:pi:101j, 0:2 * pi:101j]
x = r * sin(phi) * cos(theta)
y = r * sin(phi) * sin(theta)
z = r * cos(phi)
return (x,y,z)

*"**Claiming that something can move faster than light is a good
conversation-stopper in physics. People edge away from you in cocktail
parties; friends never return phone calls. You just don’t mess with Albert
Einstein.**"*
Over my years of using yt I have created many derived fields that are dependant on other derived fields and have various scripts that use them. So I have compiled all the definitions of fields and the yt.add_field() lines into one script which is now a module. One problem I have encountered is that, it doesn't seem that the derivation of these fields has been parallelised, as made evident by the fact that the time for ds.derived_field_list to run is independent of the number of processors available, even with yt.enable_parallelism(). Is this something that is planned to be implemented in the future?
This problem is further aggravated by the fact that after loading a file and attempting to obtain one of the fields (e.g. dd['Corrected_val_x']) seems to actually force the calculation of every possible field added to yt.
Has anyone determined a faster way of loading multiple derived fields?
Hi All
I have been searching the documentation and can’t seem to figure out how to do this! Essentially I have a star defined via its density, and I define the edge of the star as to where the density has fallen to 5% of the max value. I calculate this radius using rays. The star has a different ‘edge’ depending on what direction (x,y,z) you take the ray as it is the result of a collision. I want to take in the 3 values for the edges, and sketch an ellipsoid that covers this definition. I then want to integrate this ellipsoid to find the total value of density. I use amr so total_quantity won’t work.
So I essentially want a weighted variable sum for an ellipsoid.
Can anyone help?
Thanks
James
I'm having some trouble saving pdfs that are transparent using .save() with any of the PlotContainer inherited classes.
Typically when I have access to the entire figure, plt.savefig has an optional argument Transparent=True that returns the desired result. I've tried to get the underlying figure with my SlicePlot for example, but I also have additional annotations (contours) and I'm not sure how to add these to the underlying figure in order to use plt.savefig.
I see that the save function in PlotContainer creates a FigureCanvasPdf object which then calls print_figure (which calls print_pdf). This function does not have an argument for transparency.
Thoughts?
I just noticed an issue that arises when loading an ART simulation when using the yt.load() command. When I use the command
ds = yt.load("VELA07/10MpcBox_csf512_a0.020.d"), I get this response
yt : [INFO ] 2018-07-25 15:59:41,434 Using root level of 14

The bottom three lines show that when I am loading the .020 snapshot, I am getting particle headers and data from entirely different snapshots.
To address this, i used the file_particle_header specification, as listed her on the Loading Data page. http://yt-project.org/doc/examining/loading_data.html
However, it appears that these commands do not support wildcards like * for reading multiple files, as when I changed my code to support this, I got this error.
P002 yt : [ERROR ] 2018-07-25 15:43:39,114 FileNotFoundError: [Errno 2] No such file or directory: '/nobackupp2/sflarkin/VELA07test/PMcrda0*'
Is there a way to specify the correct files that uses wildcards to load the proper data?
I'm having some trouble saving pdfs that are transparent using .save() with
any of the PlotContainer inherited classes.
Typically when I have access to the entire figure, plt.savefig has an
optional argument Transparent=True that returns the desired result. I've
tried to get the underlying figure with my SlicePlot for example, but I
also have additional annotations (contours) and I'm not sure how to add
these to the underlying figure in order to use plt.savefig.
I see that the save function in PlotContainer creates a FigureCanvasPdf
object which then calls print_figure (which calls print_pdf). This function
does not have an argument for transparency.
Thoughts?
We use mpi4py for parallelism:
https://yt-project.org/doc/analyzing/parallel_computation.html
We are experimenting with using dark for some things, but yt predates dask
and has its own capabilities for out of core and parallel computation.
Deeper integration with dask is amethyst g we might explore in the future
but we have no current concrete plans.
Also please direct questions like this to the mailing list (cc’d) rather
than to the mailing list admins.

Hi
novice Python user trying to get ytini (Houdini for Astronomy) up and running on my Mac.
Followed instructions, using miniconda and then installed the yt package.
Confirmed that it is correctly installed.
But from within Houdini's Python shell when I try and do an import yt I get a package not found error.
I assume my pathing is wrong.
The install directions here
http://ytini.com/getstarted.html
suggest modifying your .bash_profile which I've done after first making necessary changes.
But the directions assume there is a yt-conda directory
/Users/<userfoo>/yt-conda/bin
and also a yt-conda/sbin directory
/Users/<userfoo>/yt-conda/sbin
but I have neither. Only the following
/Users/<userfoo>/miniconda3/bin
What changes should I make to my pathing to make Houdini recognize the yt package install?
Thanks!
