xF, .kF, .kR Parameters [Fickian weight, rates (s−1)]. •
fraction swelling Absorption, as fraction swelling, for which time is sought.
time, "high" (min) A time sufficiently high ("complete" swelling). •
tol, itmax, iprt NM: max. iterations; intermediate test. •

Computes, from the model (by B&H [1978]) and from a given fraction swelling, the corresponding time, an inverse problem. (For the base problem, for which thigh ≥ 20 min, computed time will be 2.0 min.)
