 == Visualization with Paraview ==
 
-Paraview requires some data and metadata that are not currently provided in the NetCDF output. Yann has done the required modifications and will commit them soon.
+DYNAMICO, with or without XIOS, now produces files that can be directly read and visualized by Paraview.

-[https://code.zmaw.de/projects/cdo cdo] can interpolate from unstructured meshes to lat-lon grids. However it also needs in a single file data and metadata that are current split in separate files. The following commands will merge the necessary data in a single file that can be processed by cdo.

-At this point merged.nc contains the surface pressure data (ps.nc) and the metadata expected by CDO. Additional fields can be merged into the same file using 'ncks -A' provided they are associated hexagons. This includes potential temperature (theta.nc), surface geopotential (phis.nc), geopotential (phi.nc).

 This procedure is an interim solution which should be replaced by built-in output to lat-lon grids in the near future.
