Visualizing the simulation results

WarpX can write data either in plotfile format (AMReX’s native format), or in openPMD format (a common data format for Particle-In-Cell codes).

Note

This is controlled by the parameters warpx.dump_plotfiles and warpx.dump_openpmd & warpx.openpmd_backend in the section Input parameters.

This section describes some of the tools available to visualize the data:

• Visualization with yt (for plotfiles)
• Visualization with Visit (for plotfiles)
• PyQt-based visualization GUI: PICViewer (for both plotfiles and openPMD)
• Visualization with openPMD-viewer (for openPMD data)
• Advanced yt visualization, for developers (for plotfiles)
• Out-of-the-box plotting script

In addition, WarpX also has In-Situ Visualization capabilities (i.e. visualizing the data directly from the simulation, without dumping data files to disk).

• In situ Visualization with SENSEI
• In situ Visualization with Ascent

If you like the 3D rendering of laser wakefield acceleration on the WarpX documentation frontpage (which is also the avatar of the ECP-WarpX organization), you can find the serial analysis script video_yt.py as well as a parallel analysis script video_yt.py used to make a similar rendering for a beam-driven wakefield simulation, running parallel.
