ED-PIC: Add Pusher Values #172
Conversation
Adds new allowed pusher values to the `particlePush` attribute in
the ED-PIC extensions.
- `streaming` (constantly moving with initial momentum)
- `LLRK4` (reduced Laundau-Lifshitz pusher via RK4 and classical
radiation reaction,

- `none` (static particles such as probes)

Ballistic sounds more physical, I like that. I just new "free streaming" as a term used in PWFA sims, but I can change it to |

@RemiLehe thinking about it and reading e.g. the default wikipedia articles on it, yes ballistic means "free to move" but usually under forces such as the gravitational force. I think we want to avoid that impression since e.g. a "free-streaming" electron beam will not change its trajectory in background electro-magnetic fields in idealized driver models that use such a pusher. |

OK, good point. Then maybe we can change |

Good idea, that's more explicit! |

I think |
Change naming to be more explicit.
Adds new allowed pusher values for classical radiation reaktion and diagnostics to the
particlePushattribute in the ED-PIC extensions.Implements issues: #132 #139 #145

None.
Writer Changes
Writers can now switch from
otherfor these three pushers to the newly specified values.Reader Changes
Just more allowed values are known now which were previously undefined as
other.Data Converter
Per-application possible but not needed. Old files are still forward compatible to this change.
