I am forwarding this conversation to the public list to keep it open for others to join in and to build up a record that might help others.
Our new student Fabian updated our frontend and implemented particle readers. Unfortunately some details of the particle "fields" still cause some bumps that we can not get our head around.
We are now able to read fields and particles, even chunk-wise, and can work with the data we read in python scripts via the all_data() method.
Nevertheless, using the particle scatter plots such as yt.ParticlePlot seems not to work. We have some problems with unions / the "all" group and the fact that we have several particle species (e.g., "hot electrons", "cold electrons", "helium ions", "nitrogen ions", etc.)
Also since the last rebase: did someone recently change the unit system in yt? T for "Tesla" seems not to be understood any more. Is there a changelog somewhere available? Do we have to describe our data in cgs / mks?
Would someone be interested for a quick heads up via e.g., skype / web-rtc so we can ask specific questions?
Fabian is around on Tuesdays and Fridays, something like early CA time, and late GER time usually works great (e.g., 9pm-PDT / 6pm-CEST).
Our current branch HEAD can be found here (->yt->frontends->openPMD): https://bitbucket.org/C0nsultant/openpmd/src?at=yt
And an example script is attached.
Thanks a lot! Axel
