User: rhaas Date: 2010/05/16 02:54 PM Modified: /trunk/ param.ccl /trunk/src/ Newton.c, TwoPunctures.c Log: TwoPunctures: improve search for ADM masses of black holes Incorporates the additions by Barry Wardell: 1) When the bare masses are not given as parameters (give_bare_mass=no), they are calculated at double precision, but the par_m_plus and par_m_minus parameters are then only set at single precision. 2) When the bare masses have been calculated, they are printed to stdout. In some cases, the initial guess for the bare mass is printed rather than the final calculated bare mass. 3) After looking at this section of code further, it seems that the termination criterion for the bare mass search could be improved. Attached is an updated patch which implements and improved check. It now continues trying to find the bare masses until the ADM masses are within a specified tolerance of their target. Other than the change in termination criterion, the algorithm is unchanged, although I have simplified the calculation of a new bare mass guess somewhat.
