Hi Paul, <div><br></div><div>If your netcdf file is using hdf5 storage than it will not work currently. I just recently moved hdf5 out of ParaView and into VTK. This will allow me to take the final step and enable netcdf with hdf5 storage for ParaView's readers, but presently it is not ready.<br>

I just upaded VTK's netcdf from 3.6.2 to 4.1.1. In addition to the traditional C library I have also brought in the C++ version of the library (vtkNetCDF_cpp). I spent time creating the proper DLL exports, allowing even Windows developers to use the library! This provides a nicer API that developers can use when writing new netcdf readers/writers. Also with netcdf 4.x we can now potentially use HDF5 based NetCDF files. See here for the release notes for NetCDF 4. As always we value feedback from the community, feel free to report any issues. In the mean time I will be monitoring the dashboards.<br>

Does this upgrade mean that Paraview should now be able to read all files in "netcdf-4 format" (i.e. netcdf-4 data model, hdf5 file format)?<br>
<br>
I'm testing with a simple file written by a netcdf-4 example that has the following contents:<br>
<br>
paulmlocal@sara0140:~/examples$ ~/software/netcdf411/bin/ncdump -k <a href="http://simple_xy_nc4.nc" target="_blank">simple_xy_nc4.nc</a><br>
netCDF-4<br>
paulmlocal@sara0140:~/examples$ ~/software/netcdf411/bin/ncdump <a href="http://simple_xy_nc4.nc" target="_blank">simple_xy_nc4.nc</a> |head<br>
netcdf simple_xy_nc4 {<br>
dimensions:<br>
x = 60 ;<br>
y = 120 ;<br>
variables:<br>
int data(x, y) ;<br>
data:<br>
<br>
data =<br>
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20,<br>
[...]<br>
7164, 7165, 7166, 7167, 7168, 7169, 7170, 7171, 7172, 7173, 7174, 7175,<br>
7176, 7177, 7178, 7179, 7180, 7181, 7182, 7183, 7184, 7185, 7186, 7187,<br>
7188, 7189, 7190, 7191, 7192, 7193, 7194, 7195, 7196, 7197, 7198, 7199 ;<br>
}<br>
<br>
When I load this file in PV 3.8.1 the only netcdf-related option I get in the "Open Data With..." box is "POP Ocean Netcdf (rectilinear)", while the file types list in the File -> Open dialog also contains "netCDF files generic and CF conventions (*.ncdf *.nc)". Are there specific requirements for the data layout used in a netcdf file for Paraview to be able to load it?<br>
<br>
Regards,<br>
Paul<br>
