7.6.17.2.4. From_Bulk_Species

Syntax: Saturation [{of} SpeciesName] = From_Bulk_Species ([Min = min] | [Max = max])
Scope: Aria Material
Summary: Saturation computed from the bulk species concentrations
Description: Calculates the saturation from the bulk species concentrations ( $c_{b,i}$ ), partial molar volumes ( $v_i$ ), and porosity ( $\phi$ ).

$S = \frac{1}{\phi} \sum_i c_{b,i} v_i$
