Hi Marc,

I'm not surprised that yt doesn't work quite out-of-the box with Pluto data, but the Chombo HDF5 frontend definitely works, and could probably be made to handle Pluto data with minimal hassle. Probably you just need to do things like specifying the field names, where to find stuff like 'gamma', etc. If you want help with that, I'd be happy to point you to the right places in the code. It would also help if you could provide the traceback for the error you are seeing when you try to load the dataset.

Best, Andrew

Thanks for your interest in yt! I have not used yt and pluto, but I have used yt with some other Chombo data in the past. I would strongly suggest you join the yt-users mailing list, which you can do here:

http://lists.spacepope.org/listinfo.cgi/yt-users-spacepope.org

or dropping by our IRC chat room,

http://yt-project.org/irc.html

I believe Andrew Myers, who is active on yt-users, has the most experience using Chombo data in yt. However, the mailing list is the best way to get help. If you do post to yt-users, please include some details about exactly what is going wrong when you try to load your Pluto data. This will help get you going faster.

take care, and welcome to yt!

yours,

Jeff

Dear Jeff Oishi,

I would very much like to use yt for analyzing my PLUTO simulations. I saw that there is supposed to be support for the Chombo hdf5 files, but it does not seem to work for me (maybe not for PLUTO 4.0?). Do you know of anybody who is working with PLUTO + yt, I might contact?

Thanks a lot.

Best regards from Munich,

Marc

Hi Marc, Thanks for providing that sample dataset. I just submitted a pull request that should add basic support for reading in Pluto datasets, provided they are in the Chombo HDF5 output format. You should be able to get it once it's accepted. This isn't super well-tested yet, but at least I can make slices and projections from the dataset you sent in: from yt.mods import * pf = load('data.0000.hdf5') sl = SlicePlot(pf, 0, 'Density') sl.annotate_grids() sl.save() and from yt.mods import * pf = load('data.0000.hdf5') proj = ProjectionPlot(pf, 0, 'Density') proj.save() You'll probably want to modify things a bit, but that should at least get you started. The files you'll most likely need to change are these three: yt/frontends/pluto/data_structures.py yt/frontends/pluto/fields.py yt/frontends/pluto/io.py "data_structures.py" is where the grid levels and locations are read in from the hdf5 file, and also where the pluto.ini file is parsed for the domain dimensions. "fields.py" is where the basic fields are set up. Right now it mostly just includes the ones in the hdf5 file, but you'll probably want to modify this to define some derived fields and also if you have a data dump with another set of physics options. Finally, "io.py" contains the methods that actually read the data from the hdf5 file. You can look at the other frontends to see how all this stuff works. You might also find these pieces of documentation helpful: http://yt-project.org/doc/analyzing/creating_derived_fields.html http://yt-project.org/doc/advanced/creating_frontend.html Good luck, and please feel free to email the list if you need any help.

Dear Jeff, Andrew, Nathan and all,

thanks a lot.

I have put a sample data file here (including parameter files, at least the pluto.ini seems to be read):

http://www.mpe.mpg.de/~mschartm/download/

data.0000.hdf5 pluto.ini definitions.h

And the error message I receive:

It would be great if you could point me to the locations where I need to adapt the code. This would save me a lot of time.

Thanks a lot and best wishes,

Marc
