How-To Guides

Short, focused recipes for common tasks.

• Visualization & Analysis
  • Merge distributed .vtu files into a single file (ParaView)
  • Read CFmesh & VTU in Python
  • Precompute time series at fixed points → create HDF5 from CFmesh / VTU

  • Plot a synoptic magnetogram aligned to 0° Carrington (HMI / GONG)
  • Interactive 3D visualization with PyVista (alternative to ParaView)
  • Plotting utilities from precomputed HDF5 time series
  • COCONUT Reader: Post-processing and Visualization
• Boundary Conditions for Heliospheric Models
  • Create and rotate inner-boundary .dat (for EUHFORIA/ICARUS)
• Comparisons with Observations
  • Compare COCONUT with Tomographic Electron Density
  • Download STEREO tomography files
• Magnetogram Processing and Filtering
  • Magnetogram Filtering for COCONUT
