applySrc_force_MRT_d3q27 Subroutine

public subroutine applySrc_force_MRT_d3q27(fun, inState, outState, neigh, auxField, nPdfSize, iLevel, varSys, time, phyConvFac, derVarPos)

Update state with source variable "force" for MRT collision model. Force term used here is from: Chai, Z., & Zhao, T. (2012). Effect of the forcing term in the multiple-relaxation-time lattice Boltzmann equation on the shear stress or the strain rate tensor. Physical Review E, 86(1), 1–11. Force term for MRT is $$\bar{F} = M^-1 (I-0.5 S) M F'$$ and $$F'_i = w_i( (\vec{e}_i-\vec{u}*)/cs2 + (\vec{e}_i \cdot \vec{u}*)\vec{e}_i/cs4) \cdot \vec{F}$$

\vec{F} is the force that must be defined as body force per unit volume

Simuilar to derive routine but it updates the state whereas derive is used for tracking.

This subroutine's interface must match the abstract interface definition proc_apply_source in derived/mus_source_var_module.f90 in order to be callable via applySrc function pointer.
