Re: [yt-users] Particle profiles

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 Elizabeth Matthew Turk wrote:

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~

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".

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,
