.. _MISC-sec: :index:`MISC` --------------------------------------------------- The MISC table defines the solvent-saturation-dependent miscibility function :math:`f_m^s(f_s)` used to interpolate between the immiscible and the miscible sets of relative permeability functions in the :ref:`Solvent Todd-Longstaff model`, see also related :ref:`theory page`. Below is an example of the table: :: MISC 0.0 0.0 0.2 0.0 0.5 1.0 / The first column is the solvent saturation fraction in the vapour phase: .. math:: f_s = \frac{S_s}{S_v} = \frac{S_s}{S_s+S_q} :math:`f_s` must grow monotonically moving down the table, and its values must be between 0 and 1. The second column reports the corresponding values of :math:`f_m^s`, which must have values between 0 (immiscible) and 1 (miscible). The table must have at least two entries. If the MISC table is not entered, :math:`f_m^s` defaults to a linear function with null value for zero solvent saturation, and unity when the vapour is fully saturated with solvent (:math:`f_s=1`).
