[Users] question about MHD tests for GRHydro

[Bruno Giacomazzo]

Hi,
	I have some questions about the MHD version of GRHydro. Today I had a business meeting at the time of the telecon, otherwise I'd have asked them during the telecon. 

	It is my understanding that the next release of the ET will happen next week and it will contain MHD. Did you do already some tests in GR? Did you try the evolution of BNS with magnetic fields? I'd like to try to run the code with magnetized BNS and see how it compares with Whisky. As some of you know in the past I had problems with divergence cleaning (DC) when evolving BNS (strong violations of divB after the merger when the BH and the torus are formed when using AMR) and so I'm curious to see if the implementation of DC in GRHydro is more robust than the one I have in Whisky.

Thanks,
Bruno

P.S.: I will try to join the next ET telecon, so that I can get an update before coming to LSU.
