In the default mode, it uses a minimization algorithm. It can also use a flow algorithm if one sets the -parameter "mahf_flow" equal to "yes": +parameter "ahf_flow" equal to "yes": -mahf_flow = "yes" +ahf_flow = "yes" The minimization algorithm is VERY slow if one has a lot of terms in the spherical harmonics expansion (see below), but it is quite fast for a small number of terms. -The thorn is activated by adding the following lines to the -parameter file: +The thorn is activated by adding the following line to the parameter +file: -ah_persists = "yes" -minimumAHF_active = "yes" +ahfinder::ahf_active = "yes" Also, one needs to tell the routine how often we want to look for AH by using the parameter `mahf_findevery' (its @@ -44,7 +43,7 @@ default value is 1). The routine defines the grid function `mahfgrid' as: -mahfgrid = r - f(theta,phi) +ahfgrid = r - f(theta,phi) So that the surface being considered corresponds to the zero level of `mahfgrid'. The function f(theta,phi) is expanded in spherical -- cgit v1.2.3
