The definition of the variable cflux depends on the domain model and on the species formulation:
In building materials domains, the definition of cflux does not correspond to convection in the physical sense, but rather to vapor diffusion. However, this term is numerically handled like a convection flux, and is therefore included in the variable
cflux.
The definition of the variable dflux depends on the domain model and on the species formulation:
In hygroscopic porous media and building materials domains, the first term of the definition of dflux corresponds to liquid capillary flux. This term is numerically handled like a diffusion flux, and is therefore included in the variable
dflux.
