![]() When the server is launched on more than one MPI process, the reader will automatically only load a subset of the data from the netCDF file on each process. This requires using a separate ParaView Server. The LFRic reader supports MPI-based parallelisation with VTK's parallel pipelines, allowing users to visualise very large datafiles on high-performance systems. Fields on "full-level" grids are interpolated onto "half-level" grids using nearest-neighbour averaging, resulting in cell-based VTK data.Support for very large data files using parallel operation.Automatic handling of periodic grids (vertices are automatically mirrored).Visualisation using Cartesian coordinates and longitude-latitude-radius coordinates.Fields that are stored on "edge-half-level" grids can be visualised as points and glyphs (e.g., arrows).Visualisation of LFRic fields that are stored in the "full-level" and "half-level" grids.The reader currently includes the following features: If you want to see more detailed output to track down a problem, you can also rebuild the reader with -DCMAKE_BUILD_TYPE=Debug. The reader will send error messages to the error console in the ParaView GUI, and to the command line (if available). An example is included in this repository. The LFRic reader can easily by used in Python scripts like any other ParaView reader. ParaView should now allow you to choose the LFRic netCDF file reader when you open a netCDF file. You can also tick the "Auto Load" checkbox in the plugin details section, so that the reader will be automatically available next time you launch ParaView. The reader plugin should now appear in the list.Ĭlick on "Load Selected" after selecting the reader plugin, if it is not already loaded. If the reader is not shown in the list, click on "Load New.", navigate to the reader installation directory, and select the shared library. If you only run the GUI, look for the LFRic reader plugin in the "Local Plugins" section, or in the "Remote Plugins" section if you run a separate ParaView server. Using the ParaView GUI, navigate to "Tools > Manage Plugins.". The reader is a "server side" plugin, so it needs to be accessed by the ParaView Server (or by the built-in server if you simply run the ParaView GUI).
