static T plb::offEquilibriumAdvectionDiffusionTemplates< T, Descriptor >::fromJtoFneq	(	plint	iPop,
		Array< T, Descriptor< T >::d > const &	jNeq
	)			[inline, static]

Compute off-equilibrium part of the f's from the current j.

Implements the following formula (with Einstein index contraction): /f[ f_i^{neq} = t_i / (c_s^4) * (c_{ia} j_a /f] By Pi we mean the tensor computed from the off-equilibrium functions: /f[ j_a = c_{ia} f_i^{neq} = c_{ia} f_i - u_a Id /f] where u_a is an external vectorial field (the velocity for example)
