POROSITY

Example: 

POROSITY 
number_of_dl_porosities 1 
porosity_types variable constant
fix_porosity 0.3 
fix_DLporosity 0.1 
END

number_of_dl_porosities

number_of_dl_porosities integer value

The diffuse layer (DL) porosities compensate the charge of the surfaces, which they are associated to. If the simulation contains surface complexation or \(K_D\) reactions, at least one DL porosity must be present in the calculation.

porosity_types

porosity_types type type ...

The first porosity is the bulk porosity, which must be of type constant or variable. The other porosities can be of type constant, proportional, diffuse_layer, 1WL_interlayer, 2WL_interlayer, or 3WL_interlayer.

The types indicated here are the default for CONDITIONS without specification of the porosity types.

fix_porosity

fix_porosity value

The value will be the default for CONDITIONS without specification of the porosity values.
