Hello Jay,
Sorry for the long delay, I had completely forgotten about your email.
Could someone kindly provide me the right parfile to be used with GRHydro in order to perform this test?
The parfiles for the MhD paper are available (carefully hidden, admittedly) via the ET page in file BondiFlowBase.rpar here:
http://einsteintoolkit.org/mp.html
which is linked as "materials" on
http://einsteintoolkit.org/publications.html
which in turn is linked as "papers" on
http://einsteintoolkit.org/documentation.html
I have verified that this parfile is the one used in the paper (or at least identical that I find in my copy of the paper svn checkout). It does not use SmoothedPuncture and will by default produce a parfile suitable for GRHydro using constrained transport (note that this is what is done in the published paper, the arXiv copy is a previous version of the paper where we used divergence cleaning, though it should be updated to match the the published version soon).
Yours, Roland
