Are you implying that if I use the HDF5 fortran wrapper to convert the fortran binary data in h5 format and then visualize this h5 file using Paraview, I am looking at the the actual data with correct dimensions? Or I have to make some modifications so that I see the data correctly in Paraview?
I dont want to transpose the data. I just want to visualize what I wrote using Fortran without any alterations.
