Interfacing User Code

CRPropa can be interfaced to user code, respectivily adapted to specialized needs in in several ways:

• Implementing additional Modules and Features using Python only
  • Manual Simulation Processing
  • Plugins: Integrate Custom C++ Code to CRPropa’s Python Steering
• Custom Observer
• Custom Photon Fields
  • Introduction
    • Downloading CRPropa-data
    • 1. Create a python class with your custom photon field (CRPropa-data)
    • Warning
      • Plotting (Optional)
    • 2. Create tables for all photon field dependent processes
    • 3. Copy files to the share folder
    • 4. Implementing custom PhotonField in CRPropa
    • 5. Check implementation
    • 6. Limitation
• Position-dependent photon fields / 1 - Generating a spatially-scaled power-law photon field
  • Physics background
  • Setup
  • 1. Define the homogeneous photon field (CRPropa-data)
    • Plot the field
  • 2. Generate the interaction tables (CRPropa-data)
  • 3. Scale the field in space
    • On-disk layout
    • Writers
  • 4. Generate the spatial field
  • 5. Check the implementation
    • Density gradient
    • Interaction rate
  • 6. Notes and limitations
• Position-dependent photon fields / 2 - Propagating through a spatially-scaled photon field
  • Geometry
    • Setup
  • Per-node field writers
  • Analysis helpers
    • 1. Surviving spectrum: homogeneous vs \(1/r\)-scaled
    • 2. Convergence with grid sampling
    • 3. Notes
• Using CRPropa from C++
