It looks like Import read the arrays, but hasn't created the fields you need.
There are limitations in what the netCDF importer handles, as has been discussed in this e-mail group. There are specific conventions, which are outlined in the documentation, which can also help. (See http://www.research.ibm.com/dx/docs/legacyhtml/pages/usrgu067.htm and http://www.research.ibm.com/dx/docs/legacyhtml/pages/usrgu068.htm for details.) It looks like your first group has the positions component you need and the second group various data components. I assume somewhere you have connectivity information. You'll need to define the grid (positions and connections) on which the different variables are defined.

To do this, I compiled a DX version of my own. First I installed a netcdf-version. Also I tried the binary-version of DX for suse-linux. My problem: netcdump and netgen are working and DX also do. But I can't read any kind of NetCDF-file with DX. Mostly I get the following messages: 0: WARNING: no 'field' attributes; importing all netCDF variables Object Description: Input object is a Group which contains 7 members. member 0 is named points_of_tetraeders member 1 is named points_of_surfacetriangles member 2 is named boundarymarker_of_surfaces member 3 is named boundarypanel_of_surfaces member 4 is named points_xc member 5 is named points_yc member 6 is named points_zc Input is not ready to be rendered because 7 Fields in the Input object do not have colors yet. Use the `AutoColor', `AutoGreyScale', or `Color' modules to add colors. --------------------------------------------------------- Input object is a Group which contains 27 members. member 0 is named aa member 1 is named bb member 2 is named cc member 3 is named cd member 4 is named ce ... member 22 is named vv member 23 is named uu member 24 is named tt member 25 is named tu 0: WARNING: no 'field' attributes; importing all netCDF variables member 26 is named yet_another_variable Each group member is a Field, the basic data carrying structure in DX.

If > 3D, use the `Slice' module or `Mark' and `Compute' to reduce them to 3D or less. ECHO: Begin Execution Begin Execution 0: WARNING: no 'field' attributes; importing all netCDF variables Begin Execution 0: WARNING: no 'field' attributes; importing all netCDF variables ERROR: MapToPlane: Invalid data: lines is an invalid connections type -------------------------------------------------------- Also the testfile coming with the tar-file of NetCDF doesn't work. Is this a problem of the Binary-Version or is it all allrigth, but I have to give special options to DX? Be very pleasant for help, Greetings Martin Liu P.S. I have used the following packages: NetCDF-3.5.0 DX-4.1.3 gcc-2.95.2-98 no fortran99-compiler suse-linux 7.0, kernel-version 2.2.16 and on the other hand: opendx-4.1.0-1.suse63.i586.rpm -- ------------------------------------------------------------------ Martin Liu Deutsches Zentrum für Luft- und Raumfahrt e.V.
