[opendx-users] Importing NetCDF files with cell centered data

[Erik Engquist]

Hi, I've been looking at importing geometry data from netCDF files into
DX. It seems to work fine except for the case where the field data is
connection dependent. I can add a data component to the field and make
this component connection dependent, but any dependancy attributes added
to the field itself are ignored by the importer. Is this a weakness of
the netCDF importer, or am I missing something? 

As an example, the following works:

dimensions:
        npoints = 10 ;
        npecs = 20 ;
        ndim = 3 ;
        quad = 4 ;
variables:
        float coord(npoints, ndim) ;
        int connect(npecs, quad) ;
        float filler(npoints) ;
                filler:field = "filler, scalar" ;
                filler:connections = "connect, quads" ;
                filler:positions = "coord" ;
                filler:component = "surfcurr, data, scalar" ;
        float surfcurr(npecs) ;
                surfcurr:attributes = "dep, connections" ;

But this does not:

dimensions:
        npoints = 10 ;
        npecs = 20 ;
        ndim = 3 ;
        quad = 4 ;
variables:
        float coord(npoints, ndim) ;
        int connect(npecs, quad) ;
        float surfcurr(npecs) ;
                surfcurr:field = "surfcurr, scalar" ;
                surfcurr:connections = "connect, quads" ;
                surfcurr:positions = "coord" ;
                surfcurr:attributes = "dep, connections" ;
