trt Teiresias Radiative Transfer 1.0 (Beta)

Directions for Use:

1. Compile as described in `docs/SETUP.md`
2. Copy file `examples/input.txt` and configure with required parameters, with -inputname referring to the location of your hydro simulation. Make sure you performed the BHAC hydro simulation with the setting convert_type = 'vtuBmpi' in &filelist in amrvac.par, to give point-based output.
3. Possible modes are `-tobs`, with a fixed time grid, and `-tvar`, which requires input of observation time points.
4. Run with `./main -f input.txt > <OUTPUT FILE NAME>`.
5. The results of the relativistic radiative transfer simulation will have been written to the output file.
6. Optionally, the `video.py` script may be used for visualisation: `python video.py <OUTPUT FILE NAME>.

Done:

• Configuration arguments via command line or file.
• Efficient synchrotron microphyics from Fouka (2014).
• Hydrosimulation 1D datastructure module for input from BHAC.
• A beam datastructure.
• Boosting of emission and absorption coefficients.
• A set of beams datastructure.
• An output module
• A coherent mainfile:
  • (t_obs, a) grid mode
  • Random points as input via std input.
• Pressure / rho cut-off value.

Testing stage:

• A beam integrator.
• Test whether Synge EOS gives sensible results

Under development:

• 1.5D and 2D Radiative Transfer.

To-do:

• More documentation.
