The relationship between the SGS and body.J

The body.J is defined as a 3x3 Jacobian matrix, while SGS is the sub-grids scale contributions, a 3-dimensional vector.
Why after the SGS contirbution is calculated, Assign SGS to body.J for use by FLOWVPM ( Bi[i].J[0] += SGS[0]; Bi[i].J[1] += SGS[1]; Bi[i].J[2] += SGS[2];)
