public subroutine applySrc_force_MRT_d2q9(fun, inState, outState, neigh, auxField, nPdfSize, iLevel, varSys, time, phyConvFac, derVarPos)

Update state with source variable "force" for d3q19 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 and

Force 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_type_module.f90 in order to be callable via applySrc function pointer.
