EffectiveSaturation

Source: models/porous_flow/EffectiveSaturation.py

Define the effective saturation, taking the form of \(S = \frac{\frac{\phi}{\phi_\mathrm{max}} - S_r}{1-S_r}\) where \(\phi\) is the volume fraction of the flowing fluid, \(\phi_\mathrm{max}\) is the maximum allowable volume fraction, and \(S_r\) is the residual saturation.
