David, The way you are attempting to specify coordinates does not follow the CF convention. Your variables have a “coordinates” property that simply says “zc.” That is not sufficient in the CF convention to use that as a Z coordinate to add to the other independent coordinates. In fact, I cannot find any part of the CF convention (http://cfconventions.org/latest.html) that allows you to arbitrarily assign a Z coordinate to a 2D grid.
That said, accomplishing what you want is easy with ParaView. Just load your data like you are now (so it comes in as a flat rectilinear grid). Then run the “Warp By Scalar” filter and set the “Scalars” property to “zc”. That will apply the elevation to your data like you want. -Ken From: David Deepwell [mailto:ddeepw...@uwaterloo.ca] Sent: Saturday, December 9, 2017 12:54 PM To: Moreland, Kenneth <kmo...@sandia.gov> Cc: David Deepwell <ddeepw...@uwaterloo.ca>; paraview@paraview.org Subject: [EXTERNAL] Re: [Paraview] curvilinear CF conventions Hi Ken, I’ve attached a file which I think satisfies the curvilinear CF conventions. The grid is 2 dimensional where the z coordinate (called zc) depends on the horizontal and vertical dimensions (x and z).

There is not enough information in your email to determine whether the issue is with the ParaView reader or an issue with the data file. It would be helpful if you could send us an example file so we can replicate your problem. -Ken Sent from my iPad On Dec 9, 2017, at 9:12 AM, David Deepwell <ddeepw...@uwaterloo.ca<mailto:ddeepw...@uwaterloo.ca>> wrote: Hi all, I have a netcdf file that follows the CF conventions in curvilinear (structured) coordinates. Paraview however doesn’t recognize the auxiliary variable as the grid variable on which the rest of the fields should be plotted on. I’m not sure if this a bug with paraview misinterpreting the CF convention or if I just happen to have an attribute missing that Paraview is looking for.
