Different magnetic fields models #409

Closed cainaoliveira closed 1 year ago

cainaoliveira commented 1 year ago

Hi, I would like to know if it is possible to include different magnetic field models in the simulations in a simple way. For example, sinusoidal magnetic fields (in space).

Thank you very much in advance, Cainã

Hi Cainã, thank you for your question, yes that is possible, the most generic way to use new magnetic fields could be to load a discretized version of that field from a file onto the 3d vector grid Grid3f that CRPropa offers, in that case you could sample the desired field e.g. with python and save it into a txt file, that can afterwards be loaded into CRPropa. Another possibility would be to write a new magnetic field module, that could then be included into the simulation like the existing magnetic field modules provided. Cheers, Leander
