[Paraview] [EXTERNAL] netcdf reader

[Moreland, Kenneth]

This all depends on the structure of your netCDF file.  NetCDF is a general format that stores some set of named multidimensional arrays with attributes.  Generally when you write a netCDF file you need to follow some convention that provides semantic meaning to these arrays.

Given no other information, the default ParaView netCDF reader will assume that the arrays in the netCDF file represent uniform cartesian grids.  In addition, the default ParaView netCDF reader will look for attribute data conforming to the COARDS (http://ferret.wrc.noaa.gov/noaa_coop/coop_cdf_profile.html) or CF (http://cf-pcmdi.llnl.gov/) conventions.  These conventions allow you to specify spherical coordinates in terms of latitude, longitude, and height.

Subject: [EXTERNAL] [Paraview] netcdf reader

Hi,
I was having trouble reading data from a netcdf file to paraview. Is there some syntax that lets paraview know that it is reading in data in spherical coordinates? I was going through the 'help' section in paraview and found that 'if spherical coordinates is turned on' the netcdf reader will read in data in spherical coordinates. Is it something I have to implement as a part of the syntax in the input cdf file?
Leo Paul.
