• Set local distributions Advection Diffusion

• Define aliases to use the same variable for the moments (m's):

• Chimera transform from distributions to central moments as defined in Eq. (43)-(45) in [ M. Geier et al. (2015), DOI:10.1016/j.camwa.2015.05.001 ]

• Factorized central moments for Advection Diffusion Equation - Eq. (15)-(16) in [ X. Yang et al. (2016), DOI: 10.1016/j.advwatres.2015.09.015]

• Chimera transform from central moments to distributions as defined in Eq. (88)-(96) in [ M. Geier et al. (2015), DOI:10.1016/j.camwa.2015.05.001 ]
