Radiation Transport

Ernazar gave presentation Current Methods and Implementations of Radiation Transport Codes in Relativity
Most promising for ET apart from leakage: either truncated multipole, or 3D monte-carlo
Interested in actual implementation: Ernazar, Christian R., Frank L.

MHD

Roland implemented (unigrid) constraint transport
Tanja started to implement vector potential method (at cell centers)
Christian R. would look into extending Carpet to include prolongation/restriction operators to support full constraint transport and/or vector potential on the edges
Frank cleaned up a couple of identified old stuff

EOS

EOSG_Base is not used
- Will be archived
EOS_Base is still used by Whisky/GaTech code, and is unlikely to be discontinued there
- Will not be supported in the future by the ET, but will remain in Cactus
EOS_Omni
- Is not fully implemented - should be not a lot of work but is not needed atm
- Josh fixed/added some missing EOS/MHD variants
Todo
- test, test, test EOS+MHD
- fix NS with hot EOS
- handle multiple compositions (for supernovae collapse)
