Hi, I'd like to plot dark matter particle density as a function of radius for my particle-only simulation. Can I use add_profile_sphere, but for particles rather than gas? I only have a single halo and I know the halo it's centred in the middle of my box (or it better be, since I put it there!). Is this possible? Thanks, Elizabeth
Hi Elizabeth, It should be. You can either do the CIC deposited DM density using the field "particle_density_pyx" ( http://yt.enzotools.org/doc/api/field_list.html#particle-density-pyx ) if you're on the 'stable' branch of the field "particle_density" if you're on the current development trunk. That will convert the DM to be like a baryon quantity. If you'd rather do raw particle binning, there is also functionality for that by using the x field "ParticleRadius" ( http://yt.enzotools.org/doc/api/field_list.html#particleradius ) or one of its derivatives, and the y field "ParticleMassMsun". -Matt On Mon, Oct 25, 2010 at 5:27 PM, Elizabeth Tasker <taskere@mcmaster.ca> wrote:

I believe you can use the field "Dark_Matter_Density" with add_profile_sphere, i.e.: pc.add_profile_sphere(25.0, "kpc",["RadiusMpc", "Dark_Matter_Density"], x_bounds = (4e-4, 0.025)) Christine On Mon, 2010-10-25 at 20:27 -0400, Elizabeth Tasker wrote:

Yeah ... my face is a bit red. This solution will almost certainly work, and if it does it will be much faster. In Enzo, the Dark_Matter_Density field (if it's in your output) is a pre-computed deposited field -- the same thing as particle_density[_pyx], except without having to compute it on the fly in yt. Thanks, Christine! :) -Matt On Mon, Oct 25, 2010 at 5:39 PM, Christine Simpson <csimpson@astro.columbia.edu> wrote:

Hi Christine and Matt, Unfortunately, I don't have a Dark_Matter_Density field, just the position, velocities, type, mass and index. (From looking directly at the contents of XXXX.cpu0000). I'm afraid I also need my hand held more to use Matt's suggestion! Would it be possible to give me an example of how to call those functions? I tried to guess and failed miserably.

To expand a little on what Matt said ealier, if you don't have the Dark_Matter_Density field, you should still be able to use the field particle_density_pyx. This uses a yt implementation of the cic_deposit routine to take the particle data and make a grid field out of it. Depending on the version of yt you're using, the field will either be called particle_density_pyx or just particle_density.

Looks like yt doesn't understand your units. It should understand all the units in Enzo 2.0, so if you could off-list send me your parameter file that'd be great. I think what's probably happening is that it's a dark matter only simulation, but since yt relies on the DensityCGS conversion factor Enzo provides to convert code density (which particles are stored in) to CGS density, it doesn't know how to deal since Enzo provides no explicit Density conversion factor. -Matt On Tue, Oct 26, 2010 at 4:13 PM, Elizabeth Tasker <taskere@mcmaster.ca> wrote:

Hi Elizabeth,
That's a bug; it actually was trying to call the Enzo CIC routines. I've fixed it in the stable branch now.

Sorry, this still isn't working for me.
I don't have the field dark_matter_density and it hates cloud in cell too!
NameError: global name 'cic_deposit' is not defined

Hi Elizabeth,
Here's a script that does it; you can get this with "yt_lodgeit.py --download=1294".

Also, on re-reading your initial question, my initial suggestion of adding a profile using "ParticleRadius" and "ParticleMassMsun" *will* function, but it's not what you wanted.
Best,
Matt

Hi Christine and Matt,
Unfortunately, I don't have a Dark_Matter_Density field, just the position, velocities, type, mass and index. (From looking directly at the contents of XXXX.cpu0000).
I'm afraid I also need my hand held more to use Matt's suggestion! Would it be possible to give me an example of how to call those functions? I tried to guess and failed miserably.
Thank you~

Hi Elizabeth,
It should be. You can either do the CIC deposited DM density using the field "particle_density_pyx" ( http://yt.enzotools.org/doc/api/field_list.html#particle-density-pyx ) if you're on the 'stable' branch of the field "particle_density" if you're on the current development trunk. That will convert the DM to be like a baryon quantity.
If you'd rather do raw particle binning, there is also functionality for that by using the x field "ParticleRadius" ( http://yt.enzotools.org/doc/api/field_list.html#particleradius ) or one of its derivatives, and the y field "ParticleMassMsun".
