Hello all,

agenda next week
================

for MHD simualtions

survey of projects
==================

* M1 - Jay, currently debugging running test runs, most of the tests working in a month, update then
* MC - Liwei, 2 months
* subcycling in time - needs reviewing, will not make it for release most likely
* CanudaX - will add to agenda, in addition to the dedicated call, 
* CapyrX - longer update in a month
* Time integrators - mostly done, currently with reviewer
* Prolongation operators - worked on by Michail, Liwei, Annamalai. No final
  product yet. Michail will present next week. Work by all groups focused on B
  field prolongation so far, A-field would be desirable for AsterX.
* Roland to set up a wiki page for prolongation operator work,
  https://github.com/EinsteinToolkit/CarpetX/wiki/mhd-prolongation-schemes


updates
-------
* Liwei is working on intergration weakrates, currently this means 2 EOS
  frameworks and 2 neutrino interaction libraries in AsterX + M1 + MC
* Lucas is busy with reviewer reports etc. for time integrators
* Jay is still debugging issues found in AsterX's M1 code for the advection
  test, Allen has provided reference data produced by WhiskyTHC
* Roland has started implementing STORAGE statements in CarpetX
* Cheng-Hsin is preparing CanudaX for inclusion in the upcoming ET release in
  May, working with Noora on CCE hookup to CarpetX. Lucas split-phase
  interpolation code (for CapyrX initially) would fit well with CCE, Lucas
  gave a short overview.
* Philipp will take a look at the paper by Balsara et al. on prolongation
  operators to present along with Michail (Toth et al.)
