Detailed Description

EXPLICIT flux F = rho B^{-1} v^n (v = (mx,my)/rho) ASSEMBLED per cell, WRITTEN at the center into fx/fy.

rho B^{-1} v = B^{-1} (rho v) = B^{-1} (mx, my): we apply B^{-1} DIRECTLY to the momentum (mx, my), which avoids the division by rho (and its rho=0 case). Device-clean NAMED functor.
