Detailed Description

Coefficients of the tensor operator A_op = I + c rho B^{-1} ASSEMBLED per cell from the fluid state and the B_z field.

Writes eps_x, eps_y (diagonal) and a_xy, a_yx (cross) in component 0 of their respective MultiFab. NAMED functor (device-clean): captures Array4 handles (POD) + scalars. s: fluid state (reads rho = s(.,.,c_rho)); bz: B_z field at the center (reads B_z = bz(.,.,0)); c_rho: component of the Density role in the state; c: theta^2 dt^2 alpha; th_dt: theta dt (for w = theta dt B_z).
