Improved BGK model (with Galilean correction term) taken from Martin Geier cumulent paper 2015 Geier, M., Schönherr, M., Pasquali, A., & Krafczyk, M. (2015). The cumulant lattice Boltzmann equation in three dimensions : Theory and validation. Computers and Mathematics with Applications.
This subroutine interface must match the abstract interface definition kernel in scheme/mus_scheme_type_module.f90 in order to be callable via [[mus_scheme_type;compute]] function pointer.
