Have had a crazy couple days.<br>> <br>> Basically, yes, you are right. xdmf_points_000*.dat gives the "x" and<br>> "y" coordinates. But, for the most part, that's not the important<br>> part -- in fact, I apologize for having given such a complex example.<br>> <br>> The basics you want are identical to "loading particle data" here:<br>> <br>> http://yt-project.org/docs/dev-3.0/examining/loading_data.html#generic-particle-data<br>> <br>> That's all that the script I was doing did, up until the point where<br>> it has the "ds" object. At that point, you can and should be able to<br>> do whatever you need to. I would recommend doing it like so:<br>> <br>> * Either decide on loading in vertex or centered data<br>> * Add in scalar fields for volume, if you have them, for the FEM mesh<br>> * Use IDW weighting (also in the script) for visualization<br>> <br>> As a note, there are places where yt will build its own mesh and<br>> indexing system; these may give incorrect results. So once you have<br>> it loaded in and have made a few projections, let's figure out what<br>> the next steps are, and how we can make sure your results are<br>> high-fidelity.<br>> <br>> -Matt<br>> <br>> On Wed, Jul 23, 2014 at 7:12 PM, Ariadna Murguia <doggies012@hotmail.com> wrote:<br>> > Hi!<br>> > I have some other questions: I'm guessing that in the xdmf_points_0000.dat<br>> > and xdmf_points_0001.dat the number 0 or 1 refers to the x coordinate and y<br>> > coordinate, but what about the other variables, do they refer to the<br>> > component x and y of the variable?
