Visualizing input and output files

Point data

Point (receiver) data are output in the ASDF file format. Please see the ASDF website for details and documentation.

Volume and surface data

Meshes and wavefield data are read and written as HDF5 files. The HDF5 library allows us to performantly access single files in parallel, as well as allowing for the portable sharing of such files. To see a visual representation of what's in these files we recommend using Paraview.

Note that we strongly recommend to download Paraview from the official website -- the versions installed through Linux package management systems often do not come with the correct libraries installed.

Files are visualized in Paraview using the XDMF standard. This is why you'll see for every mesh, surface, or volume output file used by Salvus, an associated file with the same name but with a .xdmf file suffix. It is this .xdmf file that should be opened in Paraview. When you do open such a file, you should see a dialogue box which looks similar to the following image:

The reader you require is "XDMF Reader". Selecting a different reader may cause Paraview to crash.
