Hi! I wrote a while back asking to visualize a dataset in an unstructured grid with AMR and a vtk output file. I was given a script that could do simple visualizations: http://paste.yt-project.org/show/4879/ . I tried altering it in order to visualize my data but (line 39), the number of elements in my vals array is odd, making the reshape become an error. Is there a way around it? Thank you very much Ariadna Murguia Berthier
Hi Ariadna, Are you doing 3D visualization? The simulation I was using when I wrote that script was 2D -- if yours is 3D, you will likely need to change it to 3, rather than 2, in that line. If you give a bit more info about the data (shape for instance) I can try replicating it here. -Matt On Mon, Jul 14, 2014 at 2:51 PM, Ariadna Murguia <doggies012@hotmail.com> wrote:

Hi! My data has 3 coordinates (cylindrical), although the angle is cero (so it is a 2D simulation). I changed it to 3, but still vals.size/3 is not an integer. Can you tell me the order of your data? In the simulations I'm using the first numbers correspond to the 3 coordinates of each of the cells vertex. Then, there is a number for the shape of the mesh (4 in the case of squares), followed by the list of vertex. After that, it has the values of the variables inside the square. Thank you for your help, Ariadna

Hi Ariadna, Sorry for the delay in my reply. I think that there might need to be a slight modification to the script I sent to get it working for your data. Ultimately, none of the reshaping/loading/etc matter -- the end result, where you supply particle_position_x, particle_position_y, and particle_position_z is the important part. Do you think that it would be feasible to do that with your data? And, are your data values vertex defined or cell-center defined? If the former, the technique I showed should work, but if the latter, there is likely a much easier technique to use. Today I'm going to have limited availability, but perhaps we could set up a time on Thursday or Friday to go over this in our IRC channel, with lower latency responses? -Matt On Tue, Jul 15, 2014 at 12:58 PM, Ariadna Murguia <doggies012@hotmail.com> wrote:

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

If so, what happens when dealing with a scalar?

Hi Ariadna,
Sorry for the delay in my reply. I think that there might need to be a slight modification to the script I sent to get it working for your data. Ultimately, none of the reshaping/loading/etc matter -- the end result, where you supply particle_position_x, particle_position_y, and particle_position_z is the important part. Do you think that it would be feasible to do that with your data? And, are your data values vertex defined or cell-center defined? If the former, the technique I showed should work, but if the latter, there is likely a much easier technique to use.
Today I'm going to have limited availability, but perhaps we could set up a time on Thursday or Friday to go over this in our IRC channel, with lower latency responses?

Hi! Do you think you can send me your .dat so that can see what the code is doing? Thank you! Ariadna
Are you doing 3D visualization? The simulation I was using when I wrote that script was 2D -- if yours is 3D, you will likely need to change it to 3, rather than 2, in that line. If you give a bit more info about the data (shape for instance) I can try replicating it here.

Hi! I wrote a while back asking to visualize a dataset in an unstructured grid with AMR and a vtk output file. I was given a script that could do simple visualizations: http://paste.yt-project.org/show/4879/ . I tried altering it in order to visualize my data but (line 39), the number of elements in my vals array is odd, making the reshape become an error. Is there a way around it?
