Detailed Description

~~~~ The data file for the dipole field model in MB09 is at:

http://www.cfa.harvard.edu/~jmckinney/research/dump0050

The file is aobut 1.6GB in size and from CFA took me 34mins to upload at 800KB/s.

The associated grid dump file is at:

http://www.cfa.harvard.edu/~jmckinney/research/gdump

The file is aobut 2.8GB in size and from CFA took me 61mins to upload at 800KB/s.

That data file contains a (TN1xTN2xTN3=256x128x32) data block with a 1-line header that contains (21 items):

1) t : time 2,3,4) TN1,TN2,TN3 : grid size in r,, 5,6,7) startx[1,2,3] : start of MKS grid 8,9,10) dx[1,2,3] : step for MKS grid 11) nstep: number of steps up to that point 12) : adiabatic index 13) a (BH spin) 14,15,16,17) R0, Rin, Rout, hslope : MKS grid parameters 18) dt : timestep 19) defcoord : which MKS grid used 20,21) MBH, QBH : always MBH=1 and QBH=0 for Kerr for us

After the header comes a text line break and the data cube follows in C-order such that the columns of data indexed fastest, r(i) index is next fastest, (j) index is slower, and (k) is slowest index. All quantities are at the cell center. Below NDIM=4 is the number of dimensions.

The columns correspond to (72 of them):

1-3) ti tj tk : indices in i,j,k 4-6) x1 x2 x3 : MKS-coord positions 7-9) r h ph : BL/KS-coord positions 10-17) rho,u,v1,v2,v3,B1,B2,B3 : Here v^i is relative 4-velocity defined in MG04 and B^i=*F^{it} as in MG04, both are in MKS coordinates 18-20) p,cs2,Sden: pressure,c_s^2,entropy density 21-28) U0 U1 U2 U3 U4 U5 U6 U7 : conserved quantities in MKS coordinates 29) divb : B : don't worry that non-zero on outer radial edge 30-37) uu0 uu1 uu2 uu3 ud0 ud1 ud2 ud3 : u^ and u_ in MKS 38-45) bu0 bu1 bu2 bu3 bd0 bd1 bd2 bd3 : b^ and b_ in MKS 46-51) v1m v1p v2m v2p v3m v3p : characteristic vels in 1,2,3 directions in MKS 52) gdet : {(-g)} 53-60) ju0 ju1 ju2 ju3 jd0 jd1 jd2 jd3 : j^ and j_ in MKS 61-72) fu0 fu1 fu2 fu3 fu4 fu5 fd0 fd1 fd2 fd3 fd4 fd5 : F^{} where (e.g.) fd0=F_{01}, fd1 = F_{02}, fd2 = F_{03}, fd3 = F_{12}, fd4 = F_{13}, fd5 = F_{23}

That grid file has the same structure as the data file but with a different number of columns and different functions for each column.

The columns (126 of them) correspond to:

1-3) ti tj tk : indices in i,j,k 4-6) x1 x2 x3 : MKS-coord positions 7-9) r h ph : BL/KS-coord positions +NDIM*NDIM*NDIM : ^p_{qr} where p is slowest, q faster, and r fastest. +NDIM*NDIM: g^{pq} : p slower, q faster +NDIM*NDIM: g_{pq} : p slower, q faster +1 : {-g} +NDIM: : 2nd connection (probably not important or 0) +NDIM*NDIM: dV^p/dX^q : derivative of V (t,r,,) w.r.t. X (MKS), p slower, q faster

Explicit coords are defcoord=JET3COORDS=9 and corresponds to (where V[1,2,3]={r,,}):

npow=1.0;
r1jet=2.8;
njet=0.3;
r0jet=20.0;
rsjet=80.0;
Qjet=1.3;

V[1] = R0+exp(pow(X[1],npow)) ;

myhslope=2.0-Qjet*pow(V[1]/r1jet,-njet*(0.5+1.0/M_PI*atan(V[1]/r0jet-rsjet/r0jet)));

if(X[2]<0.5){
  V[2] = M_PI * X[2] + ((1. - myhslope) / 2.) * mysin(2. * M_PI * X[2]);
}
else{
  V[2] = M_PI - (M_PI * (1.0-X[2])) + ((1. - myhslope) / 2.) * (-mysin(2. * M_PI * (1.0-X[2])));
}

V[3]=2.0*M_PI*X[3];

startx[1] = pow(log(Rin-R0),1.0/npow);
startx[2] = 0.;
startx[3] = 0.;
dx[1] = (pow(log(Rout-R0),1.0/npow)-pow(log(Rin-R0),1.0/npow)) / totalsize[1];
dx[2] = 1. / totalsize[2];
dx[3] = 1.0/totalsize[3];

To convert from MKS to KS one would do:

u^j[KS] = T^j_k u^k[MKS] where T^j_k = dV^j/dX^k as is obvious once you note that u^k = dx^k/d

u_j[KS] = [(T)^{-1}]^k_j u_k[MKS] where [(T)^{-1}]^k_j is the matrix inverse of T^j_k (no additional transpose)

The presence of the transpose or not can be determined by ensuring you always match the indices to the correct component type (MKS or KS).

Note that I use numerical recipes (NR) to do the inverse. You can use whatever you like. I don't have a separate code that does that – I've integrated NR into my code too much.

Explicit code snippets, where below dxdxp[j][k]=dV^j/dX^k

#define DLOOPA(j) for(j=0;j<NDIM;j++) #define DLOOP(j,k) for(j=0;j<NDIM;j++)for(k=0;k<NDIM;k++)
