SUBROUTINE eightwavesJ(REAL[] q, REAL[] dfdq, CELLINFO ci)

Defined In:

contrib/astro/physics/i_i_ODEs.f90

Inputs:

REAL[] q. The 1D array that holds the field values for the cell.

REAL[] dfdq. A 2D array that returns the Jacobian matrix of f with respect to the field variables in q.

CELLINFO ci. Contains info and constants used to toggle various derivative calculations.

Description:

An early attempt at clearing divergence by pushing it off the problem domain; since replaced by constrained transport. Is not implemented in 3D.

Called In:

ODEs :: Jacobian2D()
