Hello Paraview-Experts,
I am using XDMF-file-format to display flow-simulation results.
I just figured out, that XDMF is somehow mixing the dimensions :(
If I store a 3d-dataset using hdf5 in xyz-style. I have to access these
dataset using xdmf in zyx-style.
This is some kind of strange. Is there any reason for that behavior?
Greetings
Jens
Example:
HyperSlab x=32, y=64, z=128
Dataset x=128, y=256, z=512
