Hi Roland,
your patch seems correct to me if w_lorentz_2 actually represents the square of the lorentz factor. If it does, then we would have to modify in other parts of the file where it is being consistently defined as w^2=1-v^2.
Thanks. I had not noticed those.
However, I suspect that this definition of w is more in the lines of equation 2.17 of Shibata et al's PRD68, 084020 (2003). I am checking the equations again to see if this is true or not and will get back to you later.
Thank you.
Hopefully we can clear up any inconsistency there.
I was using the LRR article on GRHD, under Equ. (31):
http://relativity.livingreviews.org/Articles/lrr-2008-7/articlesu1.html#x6-3...
the PRD paper uses the four velocity u^j whereas LRR uses the three velocity.
Frank: Are TOV_Velocity_[xyz] components of u^i, u_j, or v^i (in the Valencia terminology)?
Yours, Roland
