Re: [yt-users] star_density slices

Hi Britton, I don't have any DM in my simulations, so I don't think that will produce anything? Elizabeth Britton Smith wrote:

Hi Elizabeth,

Matt and I are still puzzling over this. It's not clear right now if the issue is related to projecting particles in general in your data or projecting star particles specifically. Can you do another full box projection for us, but this time with the field dm_density? That should help us to narrow down the problem.

Hi Matt and Britton,

I've attached the image for the stars over the whole disk; it shows the same issue, with the grids (and also any gas property) showing the region correctly, but the stars only appearing in a small patch.

Matt, your script gives:

Min: [('x', 5.6774955112245706), ('y', 5.7878015648296586), ('z', 15.07668303734844)] Max: [('x', 26.537083788811703), ('y', 25.802074691296504), ('z', 17.201602159672426)]

Which are the values I expect.

It could be, as Britton suggests, a problem with the box size not being 0-1. Although, that is a particularly random patch it's decided to fill in.

Hi Elizabeth,

Weird.

This script should help us find out where the stars live. What's it give you? (Replace the loaded dataset with your own.)

Also, it'd be nice to see that image Britton requested.

Oddly, neither of those make any difference.

I would also suggest trying some projections instead of slices as well. Both of those fields are created using the CIC_deposit interpolation method with just the star particles. I could see a field like that being problematic when doing slices.

Try using the field StarMassMsun instead of star_density and see what it yields. I've had better luck with that field.

Hi,

Slices of the star_density field are only showing a tiny patch of the area in the corner, rather than the whole region. My script looks like:

pc = PlotCollection(pf, center=[17.,11.5, 16]) p = pc.add_slice("star_density", 2) pc.set_width(10, 'kpc') p.modify["grids"]()

Density comes out fine and the grids are drawn in but then only a few of them get stars.
