Hi, I have about 10 scalar fields and 10 vector fields on 17*17*17 datapoints at 1000 time steps. Each time step occupies one h5 file. I wrote an Xdmf file, which works fine in Paraview.
My problem is, my Xdmf file is about 4 MB. It takes 50 seconds to load. The "apply" properties button, takes another 15 seconds. This happens on a moderately new consumer computer (AMD Phenom 9600 quad core, 4 GB memory). Am I doing it wrong? How can I speed this up? My Xdmf file (truncated) follows below. Time step 0 is special. Time steps 1..1000 have the same data format. I repeat the same data description 1000 times. It seems redundant, but I don't know how else to do it. Thank you, Paisa <?xml version="1.0" ?> <!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []> <Xdmf xmlns:xi="http://www.w3.org/2003/XInclude"; Version="2.2"> <Information Name="SampleLocation" Value="4"/> <Domain>
