Optimized Advection relaxation routine for the MSGas BGK model for d3q19 layout with three species.
This routine contains the implementation of semi-implicit lattice boltzmann equation using variable transformation based on the paper "Multi-species Lattice Boltzmann Model and Practical Examples. Short Course material Pietro Asinari PhD." \n Refer page: Multispecies for more information In the variable tranformation steps, we can skip the step 1 and step 3 and evaluate only step 2 based on tranformed variable g only prerequisite is to compute feq which depends on original f not on g. feq is depend on density and velocity. Where density can be computed directly from g and velocity computed from linear system of equation given in the reference page Multispecies. KM: This is an non-optimized kernel
This subroutine interface must match the abstract interface definition kernel in scheme/mus_scheme_type_module.f90 in order to be callable via compute function pointer.
