+ | === Description === | ||
+ | |||
+ | Computes the **effective liquid fraction** $ f_l^{eff} $, excluding liquid entrapped inside solid grains, which does not contribute to the flow. Liquid fraction $ f_l $ is computed with Scheil law. Some liquid is released when bonds are broken, so $f_l^{eff} $ depends on the cohesion degree $ \lambda $. | ||
+ | |||
+ | $$ | ||
+ | f_l^{eff} = f_l [1-\lambda(1-f_l)] | ||
